The State of Michigan geographically dominates the Great Lakes watershed which encompasses the largest system of freshwater lakes in the world. Michigan's shoreline extends for 3,288 miles, longer than any state except Alaska. It has over 35,000 inland lakes one-tenth of an acre or larger and more than 200 rivers with a total length of 36,350 miles (Wolfson 1987). Coon (1999) listed 172 extant species of fish present in the Great Lakes and their tributaries. (Seven more occur in the St. Lawrence River and its tributaries). Of the 172 species, 153 are found in Michigan waters. Since 1919 the University of Michigan Museum of Zoology (UMMZ) has systematically collected and catalogued Michigan fishes. During these years the State of Michigan Department of Natural Resources (MDNR) and federal agencies have provided specimens to the UMMZ in the context of their studies of environmental health, angling, or commercial harvest. Early distribution maps were compiled by UMMZ, but were not readily available for use outside of the Museum. At present, with environmental concerns being addressed at the ecosystem level, it has become es- sential that the distribution and abundance of fishes be known for planning and management. This information will enhance land-use planning from the community to the state level. Distribution patterns in relation to global warming and other environmental disturbances can be considered, the influence of past geologic and climatic changes can be studied, and management plans for rare, threatened and endangered species can be made. The impact of immigrant and introduced fishes can also be assessed. Our objectives in this atlas are to provide detailed digital distribution maps by species for Michigan fishes with explicit keys and illustrations for their identification. An enonnous amount of valuable infonnation exists describing present and historical patterns of fish distributions.
