Routing the Genesee River Flood of 1972

The Mount Morris dam was constructed upstream of Rochester, NY on the Genesee River by the U.S. Army Corps of Engineers in the 1950ís to provide flood protection. In June of 1972, the remnants of Hurricane Agnes stalled over New York from June 20th to June 25th. During this time the Genesee River watershed experienced 3 to 16 inches of rainfall, and the Mount Morris dam filled up to less than 5 feet from the top before water was released. The floodwaters can be routed going into the dam at Portageville, NY, as the dam fills up, and as they exit the dam at Rochester, NY. If all the floodwater from this event had traveled from the southern tier into Rochester, or if the dam had been overtopped; major damage would have occurred near Rochester. Puls flood routing correctly predicts the success of the Mount Morris dam for this event.
