The Mount Morris Dam, situated deep in the Genesee River gorge near the northern end of Letchworth State Park in Livingston County, NY, has been very effective at reducing the risk of flooding for downstream communities since it was built in 1952. In fact, to date, the dam has prevented over $3 billion worth of flood damages. The U.S. Army Corps of Engineers Buffalo District is responsible for maintaining the dam so that it continues to perform this valuable flood risk reduction mission.
