East Branch Clarion River Lake, or East Branch Lake is a reservoir at Elk State Park in Elk County, Pennsylvania, in the United States. It was constructed by the U.S. Army Corps of Engineers by damming the East Branch of the Clarion River. Construction of the rolled earth, impervious core dam was authorized by the Flood Control Act of 1944. The lake is one of sixteen flood control projects administered by the Pittsburgh District of the Army Corps of Engineers. East Branch Clarion River Lake helps to provide flood protection for the Clarion River valley and the lower portions of the Allegheny River and the upper portions of the Ohio River. The dam is 7.3 mi (11.7 km) upstream from the confluence of the East and West branches of the Clarion River. It was constructed in 1952 for $9 million and serves a 72.4 mi2 (187 km2) drainage area. It is estimated that East Branch Clarion River Lake has prevented $81 million in damage. The dam was especially important in curtailing damage during the 1972 floods caused by Hurricane Agnes. East Branch Clarion River Lake also serves recreational purposes.
