Water resources data for Michigan, water year 1985

Water resources data for the 1985 water year for Michigan consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water temperature of ground water. This report contains discharge records for 135 gaging stations; stage only records for 1 gaging station; stage and contents for 5 lakes and reservoirs; water-quality records for 52 gaging stations; water-level records for 53 observation wells; and water-temperature records for 6 observation wells. Also included are 52 crest-stage partial-record stations and 30 low-flow partial-record stations. Additional water data were collected at various sites not involved in the systematic data-collection program. Miscellaneous data were collected at 41 measuring sites and 1 water-quality sampling site. These data represent that part of the National Water Data System collected by the U.S. Geological Survey and cooperating State, Local, and Federal agencies in Michigan.

Compilation of data for Michigan lakes

Michigan's more than 11,000 lakes are a valuable resource. Primarily, they are used for recreation but many have potential for industrial use and for water supply. Lakes have water surfaces ·that expand and decrease in area, and levels that rise and fall. Records of lakes levels show that lake stages change, have seasonal trends, and may fluctuate several feet each year. Often; these changes affect the use of lakes and cause erosion of their shorelines. It is important, therefore, to monitor lake levels in order to add to their understanding and to provide a basis for increasing their usefulness. In the early 1940's, and in cooperation with the Michigan Department of Natural Resources, a network of lake gages was established in Michigan to observe lake levels. In subsequent years, this network of lake gages was changed to provide a broad areal coverage of lakes in the State, to answer specific requests for data, and to obtain information on a large portion of Michigan's many lakes. These data have been applied primarily in studies involving the design of lake-level control facilities and establishing legal levels for lakes.
