As part of the National Water-Use Information Program, the U.S. Geological Survey (USGS) stores water-use data in standardized format for different catego ries of water use. Information about amounts of water withdrawn, sources of wa ter, how the water was used, and how much water was returned is available to those involved in establishing water-resource policy and to those managing water resources. In 1978, the USGS entered into a cooperative program with the Wisconsin De partment of Natural Resources (WDNR) to inventory water use in Wisconsin. Since that time, four reports summarizing water use have been published (Law rence and Ellefson, 1982; Ellefson and others, 1987; Ellefson and others, 1993; Ellefson and others, 1997). Ellefson and others (1997) present 1995 water-use data in a map and graph format. Because water use changes with time, an update report is periodically required. This report presents 2000 data in the same format as the 1997 report.
