Allegheny National Forest
Warren, Warren County, PA., USA
The Kinzua Dam, in the Allegheny National Forest in Warren County, Pennsylvania, is one of the largest dams in the United States east of the Mississippi River.
The dam is located 6 miles (10 km) east of Warren, Pennsylvania along Route 59, within the 500,000-acre (2,000 km2) Allegheny National Forest. A boat marina and beach are located within the dam boundaries. In addition to providing flood control and power generation, the dam created Pennsylvania's deepest lake, the Allegheny Reservoir, also known as Kinzua Lake
Authorized by the Flood Control Acts of 1936 and 1938, actual construction on the dam was begun by the US Army Corps of Engineers in 1960 and completed in 1965. The main purpose of the dam is flood control on the Allegheny River. Kinzua controls drainage on a watershed of 2,180 square miles (5,650 km2), an area twice the size of the state of Rhode Island. Side benefits derived from the dam include drought control, hydroelectric power production, and recreation.
