Management of water surface elevations at 27 dams affects much of the floodplain habitat in a 653-mi stretch of the Upper Mississippi River (UMR) between St. Louis, Missouri, and Minneapolis, Minnesota. In 1930, Congress authorized most of these dams to maintain a 9-foot navigation channel. This report provides a systemic overview of current operating plans at dams on the UMR and analyzes historical data to determine how well the operating plans are being met. Water level elevations at all 27 dams on the UMR are regulated as a function of discharge, although plans are specific for each dam. The U.S. Army Corps of Engineers strives to maintain a target water level at a specific location in a pool (control point) over a specific range [...]
