Introduction and Overview                                   
Michigan is characterized by magnificent water resources.   
The Great Lakes and inland lakes and rivers have            
distinctively shaped Michigan's transportation system,      
economy, history, quality of life and life style.           
Abundant and accessible resources for boating, swimming,    
fishing, scuba diving and scenic enjoyment have helped      
create a life style found only in Michigan and small        
portions of other states.                                   

This report evaluates the status and potential of           
Michigan's boating and underwater recreation resources.     
It considers their physical condition, their economic and   
social importance, and direct and indirect uses (e.g.,      
scenic enjoyment). Successive sections evaluate boating     
resources, underwater resources, swimming resources and     
the role of boating/swimming/underwater resources in        
community development.                                      

Some highlights:                                            
-Major portions of Michigan's economy depend on boating,    
swimming and other water-related recreation.                

-Boating-related spending: about $3 billion per year.       

-Outdoor swimming and scuba diving-related spending:        
about $.5 billion per year.                                 

-Scenic enjoyment of boating/swimming/underwater            
resources: probably several billion dollars annually        
(c.f. coastal, shoreline and riparian real estate           
values).                                                    

Spending for these water-related recreation activities      
easily comprises a $5 billion slice of Michigan's $200      
billion annual gross domestic product. Counting secondary   
economic impacts, spending for recreational and aesthetic   
enjoyment of Michigan's water resources generates up to     
$10 billion-about 5 percent-of Michigan's economic          
activity. This spending is the economic lifeblood of        
hundreds of rural Michigan communities. Without these       
water-based recreation resources, Michigan's combined       
recreation and tourism industry would resemble that of      
Indiana, Illinois or Iowa.                                  

***Michigan clearly leads other states in boating and       
boating resources. Michigan has far more coastal            
shoreline and far more surface water than any other state   
except Alaska. It also has more registered boats than any   
other state_843,900 in 1993_and a wealth of  boating        
facilities. Boating use has grown rapidly through the       
1970s and 1980s, and is  projected to continue growing      
through the 1990s. Michigan's estimated 59 million user     
days in 1986 was projected to reach about 76 million in     
1996.1                                                      

***Michigan is a leading state for shipwreck diving and     
underwater historic preservation.Nine underwater            
preserves comprise over 2,000 square miles of Michigan's    
Great Lakes bottomlands. Over 1,300 shipwrecks are held     
in public trust in Michigan_one of the Largest and most     
pristine collections on earth.                              

***Michigan is probably also a leader in natural            
resource-based swimming and related  recreation, but few    
statistics are available.                                   

Boating                                                     

The following section presents an overview of               
recreational boating in Michigan. It first describes        
Michigan's national lead in boating, and boating's          
leading role in Michigan's economy. Other subsections       
describe Michigan's boating resources and facilities,       
boating fleet, boat owners, patterns and trends in          
boating activity, and boating's economic impacts. These     
subsections are derived largely from the Talhelm (1991)     
report on the latest statewide survey. A new survey is      
underway at Michigan State University in 1994 to update     
these use estimates and most other boating and marina       
data provided in this report, but results were not          
available in time for this publication. The boating         
section concludes with a discussion of boating-related      
opportunities and needs, derived largely from a 1991        
conference on Michigan's boating-related problems, issues   
and needs convened by then Congressman Robert W. Davis.     
Following the boating section, other sections discuss       
underwater preserves and recreational scuba diving,         
swimming and the role of boating/swimming/underwater        
resources in community development.                         

Michigan: The Leading Boating State                         

According to the U.S. Coast Guard, Michigan leads the       
nation in number of registered watercraft (Table 1). This   
can be attributed to the relatively easy access that        
Michigan's nine million residents have to the state's       
Great Lakes waters, thousands of inland lakes, and          
thousands of miles of rivers (Table 2). In 1993, 874,818    
boats were listed on the Michigan Secretary of State's      
boat registration files.                                    

Boating is one of the most common recreation activities     
in Michigan. The average Michigan resident boats in         
Michigan about eight days per year. In 1986, an estimated   
598,000 registered boats were used in Michigan on 30        
million boat-days, providing 76 million person-days of      
recreational activity (Table 3). Boating on unregistered    
boats was not estimated.                                    

The Coast Guard's comparison between states (Table 1) is    
probably misleading. For instance, in 1986, 710,323 boats   
were listed by the Michigan Secretary of State office       
(Table 3), but that number included 72,823 registrations    
that expired before 1986 and were never renewed. Only       
637,500 boats had registrations valid for 1986. Michigan    
boat registrations are valid for three years, and some      
boats are "put to rest" by their owners while the boats'    
registrations are still valid. It is not clear whether      
other states retain expired registrations on their lists.   
Further, registration procedures and the types of boats     
required to be registered vary from state to state, so it   
is unclear how to interpret the state-by-state comparison   
of boat registration numbers in Table 1. In addition,       
only an estimated 598,000 of the 637,500 validly            
registered boats were used in Michigan in 1986 (Table 3).   
Some 39,500 registered boats were completely inactive       
that year. Some owners do not use their boats in any        
given year for a variety of reasons.                        

Economic Importance                                         

Not only is Michigan a mecca for boaters, but boating is    
one of the larger "industries" in Michigan's economy.       
Owners of registered boats spent an estimated $1.83 to $2   
billion in Michigan for boating in 1986 (Table 4). Actual   
1986 spending was probably about $2 billion, since the      
statistics in Table 4 omit some boat sales in Michigan.     
Furthermore, since these expenditures had a secondary       
impact as a result of the dollars being respent within      
the state, boating had a total impact of about $3 to $4     
billion on Michigan's economy in 1986.                      

Considering the approximately 33 percent inflation in       
consumer prices since 1986, this spending would be about    
$2.67 billion in 1994 dollars, and total impact would be    
about $4 to $5.3 billion. If boating participation          
continues to increase as projected_as indicated by a 23     
percent increase in boat registration numbers since         
1986_boating-related spending in Michigan in 1994 could     
easily exceed $3 billion. Therefore, the total annual       
economic impact of boating is about $5 billion_2.5          
percent of Michigan's $200 billion gross state product.     
Approximately two-thirds to three-quarters of this money    
is spent in the retail sector, and most of the rest in      
the services sector. (Recreation and tourism are not        
usually identified as a separable sector of the economy.)   

Though Michigan has larger boat registration numbers than   
other states (according to U.S. Coast Guard statistics),    
it ranks third nationally in marine sales. Sales volumes    
vary considerably from year to year, depending on           
economic conditions. In turn, boating-related employment    
and business vary with sales volumes. In 1988, Michigan     
had 223 boat dealerships employing about 1,800 persons.     

Boating Facilities in Michigan                              

Michigan's boating facilities include recreational          
harbors of refuge, public access sites and marinas.         
Michigan currently has 86 Great Lakes recreational          
harbors (Figure 1) and 1,406 public access sites (Table     
2). Some 700 public and private marinas, yacht clubs and    
similar facilities on the Great Lakes or inland waters      
are under lease or permit with the state, in accordance     
with the Inland Lakes and Streams Act. A significant but    
unknown number of marinas operate without required          
permits, and an unknown number of marinas are not           
required to register under the Act (i.e., those that are    
too small or are located directly on the Great Lakes        
shore, involving no inland waters) (Bennett, 1991).         

Consistent counts over time of the numbers of marinas and   
marina slips are not available. However, it is clear that   
the number and capacity of marinas has been rapidly         
growing for the last decade or two. An inventory of Great   
Lakes marinas in 1983, based solely on aerial photographs   
of the coastline, estimated that Michigan had 746           
"marinas" (including many aggregations of unrelated boat    
slips that looked like possible marinas from the air)       
containing 36,651 slips serving the Great Lakes (Table 5;   
Figure 2). Condominium marinas, in which slips are          
privately owned by the persons who keep their boats         
there, may have been the most rapidly growing type of       
marina in the late 1980s. A study of marina needs           
(Talhelm et. al., 1988b) showed that marinas were still     
in short supply in 1986. The 1986 market for commercial     
marinas would have supported up to twice the number of      
Great Lakes marina slips and up to three times the number   
of inland marina slips available at that time. Many         
marinas had long waiting lists of people who wished to      
keep their boats there. Since then, the market has          
apparently softened considerably. The marina market was     
being reassessed in MSU's 1994 study, but the results       
were not available in time for this publication.            

Michigan's Watercraft Fleet                                 

Most (72 percent) of the 637,500 boats registered for       
1986 were 16 feet long or smaller, 17 percent were 17 to    
20 feet long, 8 percent were 21 to 26 feet long, and 3      
percent were over 26 feet long (Table 3). Of the 598,000    
boats actually used, 66 percent were outboard-powered, 19   
percent were inboards and inboard/outboards, 7 percent      
were sailboats, and 8 percent were some other type of       
craft.                                                      

The number of  boats registered in Michigan has grown       
fairly steadily at about 2.5 percent to 3 percent per       
year since boats were first registered in 1960 (Table 6;    
Figure 3). This trend has continued through 1993, when      
the total of 874,818 listed boats was 23 percent higher     
than that in 1986. The level period in numbers of           
registered boats from 1977 to 1980_portrayed in Figure      
3_is attributable to a 1977 change from an annual to a      
three-year registration period rather than to a smaller     
increase in boat numbers.                                   

Characteristics of Boat Owners                              

This and the next three subsections on boating summarize    
selected results from the 1986 Michigan Recreational        
Boating Survey (Talhelm et al., 1988a). The study           
involved a mail survey of the owners of 10,089 of the       
boats registered in Michigan for the 1986 boating season.   
About half of the boat owners contacted responded. The      
survey results pertain to recreational boating activity     
in Michigan waters only and do not account for boating      
by: (1) an unknown number of unregistered boats and boats   
with expired registrations, (2) an unknown number of        
boats used in Michigan but registered in other states or    
countries, and (3) unpowered craft under 17 feet long,      
which do not have to be registered. Similar surveys were    
conducted in Michigan about every three years from 1965     
to 1980. Statewide boating patterns and needs and           
statewide marina needs have not been comprehensively        
estimated since 1986, but were being reestimated by         
Michigan State University in 1994.                          

The survey revealed that the owners of registered boats     
actually used in Michigan in 1986 had an average age of     
49.9, an average of 13.5 years of education, a median       
family income of $36,400, and a household with an average   
of 2.9 persons, including an average of 0.4 children        
under 12 (Table 7). They had owned their present boat for   
an average of 8.2 years and had owned boats of some kind    
for an average of 17.1 years. Compared to boat owners in    
1980, these boat owners were somewhat older and had more    
years of education, higher incomes, smaller households      
and fewer children under 12.                                

Owners of larger boats were more educated, were less        
likely to own a second home, had fewer young children,      
and had owned their present boat for a shorter time than    
owners of smaller boats. Further information on the         
characteristics of boat owners, including an analysis of    
demographic life cycle segments, is available in Talhelm    
et al. (1988a).                                             

Owners of larger boats spend much more than owners of       
smaller boats (Stynes et al., 1983). Therefore, Great       
Lakes boaters, with their larger boats, spend much more     
per boat and per boat-day than do inland boaters (Table     
4).                                                         

Patterns and Trends in Boating Activity                     

About 61 percent of all boating occurred on inland lakes,   
28 percent occurred on the Great Lakes, and 11 percent      
occurred on inland rivers and streams (Table 8). Most       
types of boats were used most frequently on inland lakes.   
Inboard and inboard/outboard craft and sailboats were       
used slightly more on the Great Lakes than on inland        
lakes, and canoes were used slightly more on rivers and     
streams than on inland lakes.                               

Boating in Michigan is closely associated with fishing.     
Over half (52 percent) of all boat-days involved fishing    
(Table 3), including 56 percent of Great Lakes boat-days    
and 51 percent of inland boat-days (Table 9).               
Cruising/pleasure boating accounted for 36 percent of all   
boat-days, waterskiing 10 percent, and other activities 1   
percent (Table 3).                                          

The above patterns of boating activity with respect to      
craft type, bodies of water and ancillary activities have   
remained fairly consistent over the last 15 years (Table    
9 and Figure 4). All uses have increased, with overall      
boating activity up at least 48 percent between 1980 and    
1986. During the same period on the Great Lakes, large      
boat use increased at more than twice the rate of small     
boat use. On inland waters, small boat use increased at     
nearly twice the rate of large boat use (Table 6). This     
could have resulted in part from lower fuel prices in       
1986. The percentage of boat-days on which ancillary        
recreation activities (e.g., fishing) took place remained   
relatively constant between 1980 and 1986 on both the       
Great Lakes and inland waters (Table 9).                    

Transportation and Launching of Boats                       

Most boaters kept their boats at a non-waterfront           
permanent residence and transported it to an access site.   
Some 40 percent of boats were used this way. Other common   
modes involved keeping a boat at a cottage or second home   
on an inland lake (18 percent) or at a permanent            
residence on an inland lake (14 percent). All types of      
boats followed this general pattern, though a quarter or    
more of inboard boats, inboard/outboard boats and           
sailboats were kept at marinas and yacht clubs.             

Michigan's launch sites received 5.9 million visits in      
1986, or nearly 10 visits per active boat (Table 3). The    
use of public launch sites predominated, with visitation    
roughly split between Great Lakes and inland lakes. Many    
marinas and other firms also provide boat-launching         
facilities on a commercial basis.                           

Boating Origin/Destination Patterns                         

The availability of boating resources and the proximity     
to population centers determines boating activity. In       
1986, the more populated counties and those with more       
boating resources close to population centers received      
the most boating activity (Figures 5 through 8). The        
southern half of Lower Michigan received about 58 percent   
of boat-days, the northern half of Lower Michigan about     
33 percent, and the Upper Peninsula about 9 percent.        

About 21 percent of all Michigan boat-days took place in    
a seven-county region of southeastern Michigan. Residents   
of that region generated about 30 percent of the state's    
boat-days. Wayne, Oakland and Macomb Counties generated     
more boat-days than they received, whereas Livingston,      
Monroe, St. Clair and Washtenaw counties received 11        
percent of Michigan's boat-days but generated only 9        
percent.                                                    

All state planning regions dominated by urban areas         
generated more boat-days than they received. In addition    
to southeastern Michigan, these included the Flint,         
Lansing, Saginaw-Bay City and Grand Rapids regions. All     
other regions received more boat-days than they             
generated. This was most pronounced in the northern Lower   
Peninsula, which imported over half of its boat-days.       
This area received 33 percent of the state's boat-days      
but generated only 16 percent of them.                      

Forecasts of Boating Activity                               

Boating activity in Michigan doubled between 1974 and       
1986, with an annual growth rate of about 6 percent         
(Figure 4). Barring an energy crisis, total activity was    
projected to grow at a more modest 2.3 percent per year     
for the next few years (Figure 9). Use of large boats (21   
feet long or more) grew faster than average, increasing 8   
percent per year between 1974 and 1986. Large boat use is   
projected to increase 3.4 percent per year in the near      
future (Figure 9).                                          

Forecasts were also developed of boat use under the         
following fuel price scenarios:                             
1.  Status quo: relative (i.e., deflated) fuel price        
stays the same as in 1986;                                  

2.  Energy crisis: relative fuel prices are 2.5 times       
those in 1986, approximating the initial energy crisis of   
1974 except with price rationing instead of government      
rationing; and                                              

3.  Energy glut: relative fuel prices are half those of     
1986.                                                       

The resulting projections indicate that an energy crisis    
or an energy glut could decrease or increase boating        
levels by 5 percent to 12 percent, compared to use levels   
at 1986 energy prices (Table 10). Specifically, decreases   
or increases of up to 8 percent, 12 percent, 9 percent      
and 5 percent for Great Lakes use by small and large        
boats, and for inland waters use by small and large         
boats, respectively, could be expected with such price      
variations. High unemployment rates and low personal        
income levels probably operate in concert with energy       
crises, but insufficient data were available to             
statistically separate their effects.                       

Boating-Related Opportunities and Needs                     

Michiganians vastly underestimate the economic and          
quality of life importance of boating, swimming and         
related uses, and the resources that support these uses.    
Residents are slowly discovering new and better ways to     
utilize them. Lansing's recent discovery of the potential   
value of its riverfront is an excellent example.            
Unfortunately, in too many instances these potentials are   
discovered only after resources have become contaminated    
or degraded.                                                

We choose to view boating-related opportunities for         
better protecting and utilizing boating resources from      
the perspective of potential contributions to the overall   
quality of life in Michigan. They are listed only briefly   
here, but are further discussed in the section entitled     
"The Role of Boating/Swimming/Underwater Resources in       
Community Development," below:                              

RECREATION OPPORTUNITIES AND QUALITY OF LIFE: Protecting,   
developing and "nurturing" coastal and underwater parks,    
waterfronts and related scenic and cultural resources can   
help Michigan continue to offer unparalleled recreation     
opportunities and maintain high quality of life in both     
economic and non-economic terms.                            

ECONOMIC DEVELOPMENT AND COMMUNITY REVITALIZATION:          
Michigan's unmatched resources for boating, diving,         
swimming and related activities can benefit community       
economic development and be a focus for community           
enrichment and enthusiasm. Boating, diving,  swimming and   
related activities directly and indirectly support about    
ten percent of Michigan's economy. This percentage is       
much higher in some community economies. As Grand Haven,    
Lansing and numerous other Michigan communities have        
found, attractive and useable waterfronts can be a magnet   
for community economic development and a focus for          
community beauty. For example, marinas and related          
waterfront developments attract boaters, sightseers,        
shoppers and small businesses. Well-conceived waterfront    
developments also enhance community life and stimulate      
further development, enticing new residents and             
businesses unrelated to boating.                            

In 1991, a review of boating-related issues and needs was   
conducted in a Recreational Boating Workshop sponsored by   
Congressman Robert W. Davis. This workshop convened a       
broad cross section of agencies, businesses, academics      
and boaters, so it represents perhaps the best recent       
aggregation of viewpoints from across Michigan. The         
entire Summary of Problems, Issues, Needs, and              
Recommendations Identified by the Four Workshop Groups is   
appended to this report. It forms the basis for the         
following list of boating-related barriers and issues:      

REGULATORY MAZE: Complex regulations hinder development     
of facilities and services.                                 

TAXES AND FEES: Fees and taxes can severely discourage      
use and entrepreneurship.                                   

INFRASTRUCTURE: Budget reductions threaten needed           
infrastructure development and maintenance. These needs     
range from boating access and waterfront structures to      
freeeways and other general infrastructures supporting      
our tourism industry.                                       

STATEWIDE COORDINATED STRATEGY: Public and private          
services and facilities are not well balanced with real     
demand and needs in the state. Further, statewide boating   
and marina needs have not been comprehensively estimated    
since 1986.                                                 

INFORMATION AND SUPPORT SERVICES: Communities, businesses   
and other organizations need better information for         
marketing, forecasting and other support. There is a        
critical need for university outreach and other sources     
of technical assistance and leadership.                     

TOTAL QUALITY MANAGEMENT: Communities and resource          
managers must better understand user needs, perceptions,    
and creation of high-quality, sustainable recreation and    
tourism products and services that complement other         
resource uses.                                              

BALANCING PUBLIC/PRIVATE AND LOCAL/STATE INTERESTS:         
Balancing public versus private, and local versus           
statewide interests in resource use, management and         
protection can enlarge and sustain the dividends            
Michiganians receive from recreational use of Michigan's    
water resources. For instance, local restrictions           
benefitting a few can harm overall public good.             

Underwater Preserves and Recreational Scuba Diving          

The Great Lakes comprise the largest system of surface      
freshwater on earth and contain about 5,500 cubic miles     
of water (U.S. EPA and Environment Canada, 1988). Eight     
states and the Province of Ontario own nearly all of the    
approximately 94,000 square miles of Great Lakes surface    
waters and underlying bottomlands (Table 11). Michigan      
owns about 40 percent of Great Lakes surface waters and     
bottomlands, including portions of Lake Erie, Lake Huron,   
Lake  Michigan and Lake Superior.                           

Surface waters include all waters above Great Lakes         
bottomlands, i.e., water column and surface plane of the    
water body (Meyers and Tarlock et al., 1988). Bottomlands   
are submerged lands in the Great Lakes and associated       
bays and harbors that lie below and lakeward of the         
ordinary high-water mark (MDNR, 1986). Michigan's Great     
Lakes surface waters and bottomlands are managed under a    
public trust. Public trust is defined in the                
administrative rules of Public Act 247 of 1955 (Great       
Lakes Submerged Lands Act) as "the perpetual duty of the    
state to secure to its people the prevention of             
pollution, impairment or destruction of its natural         
resources, and rights of navigation, fishing, hunting,      
and use of its lands and waters for other public            
purposes" (MDNR, 1986).                                     

Approximately 1,300 shipwrecks_comprising different types   
of commercial vessels wrecked since the mid-1800s_lie on    
Michigan's Great Lakes bottomlands (Wright, 1975). This     
number does not include hundreds of sunken pleasure         
craft. In addition, these waters hold hundreds of           
submerged wharf and dock sites, middens from shoreline      
habitation areas and prehistoric sites (Halsey, 1990).      
These cultural materials are found in excellent condition   
because the cold, fresh waters of the Great Lakes are a     
good medium for preservation (Singley, 1988).               

Because of the important historical and recreational        
values provided by these underwater cultural resources,     
Michigan Public Act 452 of 1988 and P.A. 184 of 1980        
(amending P.A. 173 of 1929) were implemented to protect     
and preserve aboriginal records and antiquities and         
abandoned property on the bottomlands of the Great Lakes.   
These acts also created a process for establishing state    
Great Lakes bottomland preserves (commonly known as         
underwater preserves). P.A. 452 is administered by the      
Land and Water Management Division of the Michigan          
Department of Natural  Resources (MDNR) and the Bureau of   
Michigan History of the Michigan Department of State.       
State ownership and public trust management authority for   
shipwrecks was affirmed by the U.S. Abandoned Shipwreck     
Act of 1987 (43 U.S.C. 2101 et seq.) (Vrana and Mahoney,    
1993).                                                      

Recreational scuba diving (i.e., swimming with              
self-contained underwater breathing apparatus) on Great     
Lakes shipwrecks began in the 1950s and has increased       
dramatically to the present. An estimated four million      
active recreational divers reside in the United States      
today (Professional Association of Diving Instructors,      
personal communication, 1994). Profiles indicate that       
recreational divers have relatively high household          
incomes, educational levels and travel frequencies          
(Vrana, 1992; Skin Diver, 1989; Peterson et al., 1987a).    

A survey of the large population of recreational divers     
subscribing to Skin Diver magazine indicates that over      
half of the respondents have a four-year college degree,    
20 percent have a graduate degree, nearly 70 percent have   
an annual household income of $45,000 or greater, and       
nearly 25 percent have an annual household income of        
$90,000 or greater (Vrana, 1992). About 22 percent of the   
respondents had taken five or more diving trips within      
the twelve months prior to completing the questionnaire     
(Vrana, 1992). Skin Diver magazine (1989) reported that     
subscribers have an average household income of $64,300     
and spend an average total of $2,150 annually on 5 dive     
trips in the continental United States and some             
international travel. Peterson et al. (1987a) indicate      
that Great Lakes recreational divers averaged over 4        
trips annually to Great Lakes destinations, and spent       
nearly $250 per trip in 1986. Most of this spending was     
for goods and services that were NOT directly related to    
diving activity (Peterson et al., 1987a). Peterson et al.   
(1987b) found that divers traveled to Michigan underwater   
preserves from 14 states and Ontario, and used a variety    
of community-based services (about 50 percent used          
charter boats) and accommodations (especially motels and    
campgrounds). Kinnunen (1984, 1985) estimated that 6,000    
divers visited Alger Underwater Preserve each year in       
1984 and 1985. At $250 per trip, they would have spent      
$1.5 million per year; about half in nearby communities.    

As participation in recreational diving has increased, so   
has the establishment of Michigan underwater preserves      
(Figure 10) and the development of diving-related           
businesses (e.g., air stations, dive shops, training        
facilities, charter services) (Vrana, 1989). The prime      
attraction in underwater preserves is shipwrecks, but       
divers appear to be exploring more biological and           
geological features.                                        

There are nine state-administered underwater preserves in   
Michigan, totaling over 2,000 square miles of surface       
waters and bottomlands (Figure 10). Management and          
development activities associated with the underwater       
preserves have been coordinated predominantly by            
community-based support groups called underwater preserve   
committees (incorporated and unincorporated), in            
cooperation with the MDNR, Bureau of Michigan History,      
Michigan Sea Grant Extension, and Michigan State            
University's Department of Park, Recreation and Tourism     
Resources. These local underwater preserve committees are   
represented by the Michigan Underwater Preserves Council,   
Inc., a nonprofit corporation established to help promote   
and develop the preserves and recreational diving.          

Michigan and, to a lesser extent, the rest of the Great     
Lakes region, has become an important domestic travel       
destination for shipwreck-based recreational diving         
(Figure 11), and for maritime heritage tourism involving    
nondivers. Divers and nondivers can visit numerous          
maritime museums, interpretive centers and historical       
parks to enjoy exhibits, slide and video presentations      
and cultural demonstrations. At these and other             
locations, they can purchase publications, mementoes and    
art involving themes in maritime and shipwreck history.     
Unfortunately, very little information exists on the        
extent and characteristics of recreational diving outside   
of Michigan's underwater preserves and a few national       
park areas in the U.S. and Ontario. Very little             
information exists on the extent and characteristics of     
maritime heritage-based tourism in general, throughout      
the Great Lakes region.                                     

Important Needs and Issues                                  

Important needs and issues for Michigan underwater          
preserves and recreational scuba diving are outlined        
below. The following six informational and administrative   
needs and opportunities were developed by the authors,      
derived in part from discussions with many others:          

1.  PUBLIC-PRIVATE PARTNERSHIPS: Maintain and enhance       
public-private partnerships established among underwater    
preserve committees, the Michigan Underwater Preserves      
Council, Inc., the MDNR, the Bureau of Michigan History,    
the Michigan Travel Bureau, Michigan Sea Grant Extension    
and the MSU Department of Park,  Recreation and Tourism     
Resources. These partnerships have resulted in numerous     
benefits to underwater preserves and recreational diving    
(e.g., mooring buoy systems, cooperative advertising and    
promotion, avocational training in underwater               
archaeology, development of underwater technology for       
site mapping, marketing of recreational diving and          
involvement of the NOAA National Marine Sanctuary           
Program).                                                   

2.  ADMINISTRATIVE CLARIFICATION: Clarify the role of the   
State Parks and Recreation Division, Michigan Department    
of Natural Resources. Michigan Public Act 171 of 1899 and   
Attorney General opinions associated with underwater        
preserve legislation indicate that Michigan's Great Lakes   
waters and bottomlands are designated as a "state park      
and pleasuring ground." These broad mandates have never     
been clarified in specific administrative priorities.       
Several programs provided by the State Parks and            
Recreation Division could be expanded to benefit            
management and development of the underwater preserves      
(especially park planning, harbors of refuge and boat       
launch programs).                                           

3.  UNIVERSITY INVOLVEMENT: Increase the involvement of     
university departments and units with missions in parks,    
recreation, tourism, history and archaeology. Experience    
at  existing underwater preserves indicates that            
university programs in technical assistance, research,      
education and technology development/transfer could         
greatly benefit management and development of the           
underwater preserve system and recreational diving.         

4.  MANAGEMENT PLANNING: Develop and implement management   
plans that integrate multiple objectives for use of         
underwater preserve resources (e.g., economic               
development, recreational exploration, research, maritime   
salvage, historic preservation) to obtain sustainable       
outcomes as required by the public trust doctrine (Vrana    
and Halsey, 1992).                                          

5.  TOURISM AND RECREATION MARKETING: More effectively      
market Michigan underwater preserves as national and        
international destination areas for recreational diving.    
Determine the feasibility of marketing and developing       
maritime heritage resources within Michigan to enhance      
the tourism economy (e.g., lighthouses and lifesaving       
stations, underwater cultural resources, fishing camps      
and communities, fish and aquatic attractions,              
water-based logging operations).                            

6.  RESEARCH SUPPORT: Additional research is needed to      
estimate the extent and impacts of recreational scuba       
diving outside of Michigan's underwater preserves, such     
as other Great Lakes sites, inland lakes and streams in     
Michigan and in the Great Lakes region.                     

The following needs and issues are based on consensus of    
voting representatives attending the March 6, 1994          
business meeting of the Michigan Underwater Preserves       
Council, Inc. (MUPC):                                       

1.  Liability of MUPC membership in maintenance of          
mooring buoy systems on state owned shipwrecks and          
bottomlands.                                                

2.  Lack of statistics on use of the underwater preserves   
for recreational diving. Lack of understanding about        
impacts to underwater cultural resources from               
recreational diving activities.                             

3.  Impacts of zebra mussel colonization on underwater      
cultural resources and recreational diving.                 

4.  Return of artifacts taken from shipwreck sites and      
enforcement of laws relating to the removal of artifacts.   

5.  Intentional sinking of vessels within underwater        
preserves and other means of enhancing recreational         
diving.                                                     

The following needs were identified and prioritized by      
the community-based underwater preserve committees          
(discussed above) during 1989-1990, using the nominal       
group technique (Vrana, 1991):                              

1.  Interpretive center and/or maritime museum.             

2.  New dive sites (including intentional sinking of        
vessels).                                                   

3. Boating facilities and services.                         

4. General tourism infrastructure (facilities, services     
or attractions).                                            

5.  Site survey, documentation and mapping.                 

6.  Formal management (staff, plans and guidelines).        

7.  Marketing plans, advertising or promotion.              

8.  Scuba diving infrastructure  (shops, air services and   
charter boats).                                             

9.  Mooring buoys for dive sites.                           

10.  Law enforcement or site protection services.           

11.  Safety or emergency services.                          

Swimming                                                    

Swimming is commonly cited as one of the most popular       
recreation activities of Michigan residents and visitors    
to Michigan. Recreation activities of interest to           
residents of the Great Lakes states and Ontario when        
visiting Michigan are listed in Table 12. These results     
are from a telephone survey of households from Areas of     
Dominant Influence (ADIs) in Illinois, Indiana, Michigan,   
Minnesota, Ohio, Wisconsin, southeastern Ontario and        
western Pennsylvania (Spotts, 1991). ADIs are broadcast     
media market areas delineated by county lines.              

Swimming/sunbathing was the most common recreation          
activity in Michigan reported by Michigan residents and     
nonresident visitors in 1980-1981, at 110 million           
activity days (Table 13). This survey sampled               
approximately 1,500 Michigan resident households and        
2,000 nonresident households that visited Michigan during   
the survey year. An estimated 49 million days of            
swimming/sunbathing took place at Michigan's lakes and      
streams and the remainder at pools (Wells, 1989). In        
1976, 17 percent of lake/stream swimming by Michigan        
residents took place on Michigan's Great Lakes (Wells,      
1989).                                                      

How important are natural resources for                     
swimming/sunbathing to the quality of life in Michigan?     
How important are they to Michigan's economy? Are           
Michigan's natural resources adequately supporting the      
demand for swimming? Will they be more or less adequate     
in the future? As far as we can determine, these            
questions have never been addressed. Few data are           
available to support such an inquiry. We found very         
little scientific information on natural resource-based     
swimming activities and opportunities, particularly         
activities and opportunities on inland lakes and rivers.    

Annual expenditures for natural resource-based              
swimming/sunbathing in Michigan could easily be $500        
million per year. We could find no estimates of user        
expenditures specifically for the purpose of swimming/      
sunbathing at lakes and streams. Swimming/sunbathing is     
commonly one of several activities occurring on an outing   
that may also include picnicking and sightseeing.           
Swimming is a low-cost activity but often involves          
transportation costs, admission fees and associated         
expenditures for food, clothing and accessories. Various    
studies show that average expenditures for nonintensive     
activities such as shore and pier angling and day use       
visits to state parks are approximately $10 to $15 per      
user day. At $10 per user day and 50 million activity       
days, expenditures would be $500 million per year.          

Michigan's Great Lakes dunes and beaches are                
unquestionably a prime national swimming/sunbathing         
resource, particularly dunes and beaches in our state and   
local parks. Michigan's Great Lakes shoreline resources     
seem ample enough for some further development of natural   
resource-based swimming opportunities (Table 14), though    
approximately 80 percent of the U.S. Great Lakes            
shoreline is privately owned and not accessible to the      
public (U.S. EPA and Environment Canada, 1988). The         
percentage of shoreline in private ownership is greatest    
on the lower Great Lakes (Taylor and Gauthier, 1993; U.S.   
EPA and Environment Canada, 1988).                          

It is unclear whether public access to Great Lakes          
beaches will increase or decrease in the near future.       
Taylor and Gauthier (1993) expect continued growth over     
the next ten years in the land use categories of            
residential, commercial/industrial and public               
infrastructure along all U.S. Great Lakes and connecting    
channels, except for Lake St. Clair, which they consider    
relatively developed. These development activities could    
increase public access to the Great Lakes for swimming in   
some locations and decrease public access in other areas.   

 Recommendations by Taylor and Gauthier (1993) related to   
Great Lakes shorelands include the following:               

1.  Resources should be devoted to developing and           
implementing a strategy to maintain a land-use database.    

2.  Further analysis is required to evaluate the            
effectiveness of setback and elevation requirements and     
general development controls. Authors' note: Such           
shoreline management techniques have tremendous             
implications for public access for swimming.                

3.  Future investigations should look at the                
effectiveness of existing legislation in identifying and    
protecting areas of environmental significance or habitat   
areas. Authors' note: Shoreline recreation activities       
have been identified as a medium source of stress to        
Great Lakes biodiversity (The Nature Conservancy, 1994).    

We conclude that there is an even more basic need,          
considering the lack of information and the importance of   
natural resources-based swimming in Michigan's quality of   
life and economy_a thorough baseline inventory of           
swimming opportunities and resources, coupled with a        
comprehensive assessment of the role of these resources     
in Michigan recreation and tourism. This assessment         
should include present and future needs and opportunities   
for natural resource-based swimming in Michigan.            

Scenic Enjoyment                                            

Scenic enjoyment includes "passive" uses of boating,        
swimming, underwater and related resources in specific      
sightseeing activities, or as incidental enjoyment as       
part of other activities such as dining on or near the      
waterfront or relaxing at a waterfront cottage. In all      
cases, facilities near the water provide an endless         
source of fascination and attraction. Of course, some       
sights, smells and other sensory receptions we receive      
from these resources can be unattractive or repulsive,      
reducing the overall desirability of the resources. To      
our knowledge, no one has successfully catalogued and       
quantified all of these water-related activities, much      
less their values, either in Michigan or elsewhere.         

Some indicators of their value are obvious. First, most     
recreation activities involve using or viewing water        
resources. In Table 13, activities directly using the       
water are bold-faced. Visual use of these resources         
include nature study, picnicking, camping and visiting      
scenic sites. Tourism is closely associated with these      
resources, as indicated in Table 13 by the activity         
levels of nonresidents. Second, waterfront and riparian     
property values are typically much higher than similar      
non-waterfront, non-riparian property. Michiganians         
probably pay hundreds of millions of dollars more per       
year to own waterfront residential property for personal    
or commercial uses.                                         

These property values are only indicators of the            
importance of scenic resources and of the annual spending   
associated with them. We can only guess the potential       
dollar value of scenic uses (i.e., willingness of users     
to pay for these specific uses). The role of expenditures   
associated with scenic uses in Michigan's economy is        
probably several billion dollars per year.                  

While waterfront values are obvious, the values of the      
natural resources responsible for such scenic uses seem     
unrecognized. To our knowledge, the status and potential    
of boating/swimming/underwater resources for these          
purposes have not been explicitly addressed.                

The Role of Boating/Swimming/Underwater Resources in        
Community Development                                       

Michigan's boating, swimming, underwater and related        
scenic resources are vastly more important to Michigan's    
economy than most people realize. Roughly five to ten       
percent of Michigan's gross state product is directly or    
indirectly based on recreational uses of these resources.   
Boating-related spending is about $3 billion,               
swimming/underwater-related spending is at least $.5        
billion, and scenic enjoyment-related spending probably     
several billion dollars.                                    

There are additional indirect economic impacts. Users       
spend money in the vicinity of the resources they are       
using. Thus, billions of dollars are spent in small         
communities with attractive boating/swimming/diving         
resources and in small, waterfront areas of larger          
communities. Most of this money is spent in the retail      
and services sectors, but the secondary impacts are         
spread widely across most sectors.                          

Several Michigan communities have recognized the            
opportunity that this presents for local economic           
development. Some have capitalized on it; others have       
not. Too many communities spend thousands of dollars        
"chasing" manufacturing firms while failing to take         
advantage of major opportunities for water                  
recreation-based economic development in their own          
backyards.                                                  

Michigan's unmatched resources for boating, diving,         
swimming and related activities can increase community      
economic development and be a focus for community           
enrichment and enthusiasm. Communities have many options    
for turning water resources into accessible attractions     
that draw large numbers of residents and visitors.          
Lansing's recent discovery of the potential value of its    
riverfront is an excellent example. Lansing removed         
dilapidated facilities and trash, built a six-mile long     
riverfront trail/boardwalk, and is focusing economic        
development activities and community celebrations along     
the riverfront. Citizens and business leaders are now       
eagerly using and promoting the waterfront.                 

Marinas and related waterfront developments usually         
attract boaters, sightseers and shoppers, and small         
businesses. Well-conceived waterfront developments can      
become a nucleus for further growth, attracting new         
residents and businesses unrelated to boating. Grand        
Haven illustrates this. As its manufacturing base           
deteriorated in the 1970s, it began developing walkways     
and marinas along the waterfront. Abandoned manufacturing   
plants were converted to shopping centers, and new          
tourism-related businesses developed. Several new           
manufacturers and other businesses have since settled in    
or near Grand Haven, largely because of its attractive      
quality of life. Grand Haven also encouraged much of the    
industry remaining in its downtown waterfront to move to    
new industrial areas.                                       

Recreational divers also contribute significantly to the    
economies of small northern Michigan communities,           
especially those with nearby underwater preserves. For      
example, divers and accompanying nondivers spent an         
estimated $3.4 million in 1984 and $2.4 million in 1985     
visiting Alger County Underwater Preserve (Kinnunen,        
1984, 1985). Most of this spending benefitted businesses    
in or near the city of Munising, with a population of       
less than 3,500. Stakeholders from underwater preserve      
communities have identified important development needs     
to enhance diving- and non-diving-related                   
tourism_establishing interpretive centers and maritime      
museums, locating new dive sites, improving boating         
facilities and services, and providing better tourism       
infrastructure in general (Vrana, 1991).                    

Boating/swimming/underwater resource development can have   
broad effects on communities:                               

***Interest in maritime and underwater resources not only   
helps us learn more about our culture and history, but      
also can stimulate community development and enthusiasm.    

***Revitalizing our Great Lakes fisheries in the 1960s      
and 1970s stimulated a boating boom and a wide variety of   
economic and social change in coastal communities such as   
South Haven, Grand Haven, Munising, Rogers City and New     
Baltimore. Further  improvement in angling and boating      
quality can be expected to catalyze similar change in the   
future.                                                     

***Inland lakes and rivers have been turned from backyard   
dumps into centers of recreation, economic development      
and community pride. Many opportunities for further         
improvement remain.                                         

(1)The 1986 statewide boating survey actually estimated     
76 million boating user days in 1986, but that number       
includes 3.7 million boater-days on which boats were used   
but were not underway.  The 1986 survey also                
double-counted boating days on which the surveyed boats     
were used on both inland lakes and inland rivers or         
streams.  For projection purposes, boat-days were           
adjusted downward 15% to be consistent with a more          
conservative survey methodology used in 1980 and earlier,   
and boat use while not underway was eliminated.  These      
changes reduced the 1986 estimate to 59 million user        
days.

Recommendations from Congressman Davis' Recreational        
Boating Workshop (Park and Recreation Resources             
Department, MSU, 1991).                                     

Summary of Problems, Issues, Needs and Recommendations      
Identified by the Four Workshop Groups                      

Although the four different focus groups worked             
independently, there was considerable agreement among       
recreational boaters, industry and agencies regarding       
important recreation boating problems, issues and needs.    
There was also considerable concurrence on the actions      
they recommended to address these problems.                 

COMPLEX AND CONFUSING PROCESS FOR OBTAINING PERMITS FOR     
THE DEVELOPMENT AND EXPANSION OF RECREATION BOATING         
FACILITIES AND SERVICES                                     

Problem, Issue or Need                                      

There was agreement across all the focus groups that the    
process for obtaining permits for recreational boating      
facilities and services is complex and confusing, and       
this adds greatly to the cost of developing and expanding   
recreation boating facilities and services. Lack of         
coordination among federal, state and local agencies        
involved in permitting processes is considered to be a      
major difficulty. Participants representing industry and    
local units of government indicated that it is very         
difficult to remain current with respect to new             
environmental and operating laws, changes in existing       
laws, and agency permitting requirements.                   

Recommended Action(s)                                       

The process(es) for reviewing and issuing permits for       
recreational boating related facilities and services must   
be revised and streamlined to: (1) make them more           
understandable, (2) consolidate regulations and             
procedures, (3) coordinate the involvement of different     
federal, state and local agencies, (4) streamline the       
process(es) to reduce permit review time, (5) provide       
more emphasis on creative problem solving and assistance    
rather than denying permits, (6) hold the agencies          
accountable for (explaining) their decisions. Agencies      
should develop more effective and efficient ways of         
informing recreational boating businesses, and local        
units of government, of relevant changes in environmental   
laws, regulations and permit processes.                     

A position should be established (ombudsperson) to assist   
businesses and local units of government who encounter      
problems securing permits for recreation boating            
facilities and services.                                    

(Persons desiring to develop marinas should meet with       
Michigan Department of Natural Resources and U.S. Army      
Corps of Engineer representatives early in the conceptual   
stage of marina development to identify agency concerns     
and requirements prior to substantial commitments of        
resources. To set up a meeting, contact the MDNR Permit     
Consolidation Unit, Land and Water Management Division,     
P.O. Box 30028, Lansing, Michigan 48909, or telephone Mr.   
Les Thomas at (517)373-1950. The MDNR should continue to    
meet with the MBIA representatives on an annual basis.

NEW RECREATION BOATING RELATED TAXES AND FEES               

Problem, Issue or Need                                      

New taxes on the purchase of boats, coupled with new and    
increasing user fees are adding to the cost of              
recreational boating. Some new (and proposed) taxes and     
fees are not allocated specifically to maintenance and      
improvement of recreational boating facilities and          
services. They are being used to reduce general fund        
deficits.                                                   

Currently there is no accurate accounting of fuel taxes     
paid by recreational boaters. Questions were raised         
regarding the "equitable" distribution of fuel tax          
revenues (i.e., for recreational boating facilities and     
services).                                                  

Recommended Action(s)                                       

Before imposing new recreational boating fees and taxes,    
Congress and the Michigan Legislature should analytically   
and objectively determine the magnitude of the impact on    
recreational boaters, the recreational boating industry     
and state and local (tourism) economies.                    

Taxes and fees collected from boaters should be used to     
finance recreational boating facilities and services.       
Laws establishing new recreational boating taxes and fees   
should include a mechanism/formula to insure that the       
resulting revenues are utilized to maintain and enhance     
recreational boating facilities and services.               

There is a need for a study to accurately determine fuel    
purchased and fuel taxes paid by recreational boaters.      
The results should provide the basis for a fuel tax         
distribution formula.                                       

MAINTENANCE OF MICHIGAN'S RECREATIONAL BOATING              
INFRASTRUCTURE                                              

Problem, Issue or Need                                      

Considerable amounts of money have been invested in         
Michigan's recreational boating infrastructure including    
Harbors of Refuge, channels and waterways, public access    
sites and marinas. Reductions in agency budgets have        
diminished their ability to adequately maintain existing    
facilities, structures, channels, and waterways. Of         
special concern are reductions in funding for dredging      
operations.                                                 

Recommended Action(s)                                       

Emphasis should be directed at maintaining existing,        
rather than developing new recreational boating             
infrastructure and services. Agencies should focus their    
effort and limited resources on developing and              
maintaining facilities and services which can not be        
provided by the private sector.                             

The Army Corps of Engineers should assign greater           
priority to recreational boating (access and quality)       
when deciding on dredging priorities and resource           
allocations.                                                

Agencies/organizations responsible for law enforcement      
and search and rescue should coordinate efforts to insure   
cost effective allocation of staff and resources.           

DISTRIBUTION OF RECREATIONAL BOATING FACILITIES AND         
SERVICES                                                    

Problem, Issue or Need                                      

In some regions/areas of the state, available services      
and facilities exceed current and projected "demand." In    
other locations, there is existing and projected need for   
additional/improved access, launching facilities, Harbors   
of Refuge, marina slips, facilities and support services    
(e.g., fuel). There is a need for a more coordinated,       
cooperative and analytical approach to decisions            
regarding development and location of new recreational      
boating facilities and services, facility maintenance,      
dredging priorities, the distribution of enforcement, and   
search and rescue services.                                 

Recommended Action(s)                                       

Agencies responsible for recreational boating should        
develop (with significant involvement of industry, local    
units of government and boaters) a comprehensive,           
coordinated state-wide strategy/plan aimed at enhancing     
the quality and distribution of recreational boating        
facilities and services in Michigan. The strategy/plan      
should: (1) be based on up-to-date information on the       
"demand" and "supply" (e.g., boating access, facilities     
and services), (2) determine existing and projected         
access, facility and service needs, (3) establish           
maintenance and dredging priorities, (4) identify           
opportunities for private business development and          
public-private ventures and, (5) recommend policies,
