This is an electronic version of a publication prepared regularly by the DNR Division of Waters. The publication provides a review and summary of basic hydrologic data gathered through DNR Waters programs during the 2003 and 2004 Water Years. This report is a continuation of Water Year reports published by DNR Waters in 1979, 1980, 1991, 1993, 1995, 1997, 1999, 2001, and 2003.
There are four major areas of data collection including climatology, surface water, ground water, and water use. These topical areas follow the hydrologic cycle and provide important facts concerning the distribution and availability of Minnesota's water resources.
