Hydrologic Data For Floods of July 1978 in Southeast Minnesota and Southwest Wisconsin

Intense storms of July 1978 caused floods of historical significance in southeast Minnesota and southwest Wisconsin. Local, State, and Federal officials need data and information to evaluate, coordinate, and manage programs concerned with floods and flood losses. Because of a need to document stream discharges, elevations, and sediment concentrations, current meter and indirect measurements were made at 34 gaging stations during or immediately after the floods. This report summarizes some of the hydrologic data collected. Peak discharges of record occurred at 20 gaging stations. Frequency of peak discharge equaled or exceeded the 100-year recurrence interval at 11 stations. The Federal Benchmark gaging station on the North Fork Whitewater River was destroyed. Five people died as a result of the floods, and property damages were estimated to exceed $114 million. Thirty-three counties were officially declared disaster areas.
