Streamflow Entering and Leaving Lake Bemidji, Beltrami County, Minnesota July 1987 Through September 1989

The U.S. Geological Survey, in cooperation with the Minnesota Department of Natural Resources, operated three streamflow-gaging stations from July 1987 through September 1989 to determine the volume of streamflow entering and leaving Lake Bemidji. Suspended- and bottom-sediment data were also collected at the gaging stations. Two gaging stations were located upstream and one was located downstream from the lake. Daily mean discharges were determined except for the November 1987 to March 1988 winter period. During the 1989 water year, the only complete year of data, the mean annual discharge for the two upstream stations was 111 ft /s (cubic feet per second) for Mississippi River at Bemidji and 71 ft /s for Schoolcraft River near Bemidji. The station downstream from Lake Bemidji, Mississippi River near Bemidji, had a mean annual discharge of 228 ft /s during water year 1989.
