Great Lakes Geographic Information System Institute for Fisheries Research 20061213 Ann Arbor, MI Great Lakes Information Network (GLIN) http://gis.glin.net/ogc/services.php#lmb_mi_inland_lks_polys_dwa This dataset contains a the spatial represenations for the locations of inland lakes in Michigan, as released by Jim Breck, Michigan Department of Natural Resources, at the Institute for Fisheries Research. This shapefile is based upon an earlier version (year unknown, but likely ~2000) of Michigan's statewide Hydrography Framework, which is based upon TIGER/Line Files, MDNR MIRIS files, and the MALI dataset. Lake polygons present in this layer were edited (shape, attributes, location, duplicate representations for a lake existing in multiple counties), created for lakes that were detemined to be missing, and adjusted to reflect our current knowledge of the waterbodies throughout the state. For each lake (~10 acres or larger), a "New-Key" was assigned, based upon Humphrys and Green (1962). This unique code (e.g., 72-117), is based on the county numbers and lake numbers assigned by Humphrys and Green (1962). It serves to link these saptial representations to multiple datasets containing information pertaining to water quality, depth, origin, etc.. This dataset was developed to show location information for Michigan inland lakes 10 acres and large (and some smaller than 10 acres). In particular, this dataset was created so that area and perimeter could be calculated. Also, the New-Key (present on about ~9100 inland lakes) can be joined to other data tables, allowing the user to spatailly view associated data. It is intended for inclusion in the Digital Water Atlas of Michigan (based upon the 1:100K NHD). It is for use by state agency employees and individuals for pursuits related to the improvment of inland lake information or those assessing the state of water quality and aquatic resources in Michigan.
