Hydrologic Unit Map -- 1974, State of Michigan

Hydrologic Unit 22
Prepared in cooperation with the U.S. Water Resources Council



This map and accompanying table show Hydrologic Units that are basically hydrographic in nature.  The Cataloging Units shown will supplant the Cataloging Units previously used by the U.S. Geological Survey in its Catalog of Information on Water Data (1966-72).  The previous U.S. Geological Survey Catalog-Indexing System was by map number and letter, such as 49 M.  The boundaries shown have been adapted from "The Catalog of Information on Water Data" (1972), "Water Resources Regions and Subregions for the National Assessment of Water and Related Land Resources" by the U.S. Water Resources Council (1970), " River Basins of the United States" by the U.S. Soil Conservation Service (1963, 1970), "River Basin Maps Showing Hydrologic Stations" by the Inter-Agency Committee on Water Resources, Subcommittee on Hydrology (1961), and States planning maps.
