The spring of 2011 brought the highest water levels since the flood of 1952 and the greatest runoff volume since the U.S. Corps of Engineers began keeping records in 1898. The flood began in the spring and continued well into the summer due to the melt of a large snow accumulation during the winter and a large rain event in near Three Forks, Montana; the headwaters of the Missouri River.

All gates open on the Gavins Point Dam allowing water to pass through during the 2011 Flood. Crowds of spectators gathered on the South Dakota side to watch as water poured out from the spillway. Close to 150,000 cubic feet per second was released during the flood event.
