the dam in California

The Mount Morris Dam is a concrete gravity dam on the Genesee River. It is located at the northern end of Letchworth State Park, south of Rochester, New York in the towns of Leicester and Mount Morris in Livingston County, New York. It is the largest dam of its type east of the Mississippi River and its purpose is to mitigate downstream flooding between Mount Morris and Lake Ontario.

The Mt. Morris Dam was built between 1948 and 1952 by the Buffalo District office of the U. S. Army Corps of Engineers (USACE). The project was authorized by the United States Congress in the Flood Control Act of 1944 at a cost of $25 million. The flood of 1865, which developed flows exceeding per minute, resulted in massive destructions with flows equating to half the flows of Niagara Falls. Severe floods occurred every seven years on average between 1865 and 1950. An estimated $210 million in damages was prevented by the dam during the storm.

June 2002 commemorated the 50th anniversary of the completion of Mount Morris Dam. A celebration and dedication of the commemorative kiosk was held to honor and recognize the men and women employed by the U. S. Army Corps of Engineers, Buffalo District and Mount Morris Dam Builders, 1948–1952. The kiosk rests on a foundation of bricks, each of which is inscribed with the name and occupation of the builders.

The William B. Hoyt II Visitor Center at Mount Morris Dam, opened by the U. S. Army Corps of Engineers in 1999, was built to accommodate the thousands of people who visit the dam each year. This center features a large atrium, museum, theater and public restroom facilities.
