The Youghiogheny River Lake is a flood control reservoir in southwestern Pennsylvania and western Maryland.
The lake was formed in 1944 by the damming of the Youghiogheny River upstream from Confluence, Pennsylvania. Youghiogheny Dam is an earthen structure, 184 feet high and 1610 long at its crest, owned and operated by the United States Army Corps of Engineers. The reservoir's normal surface area is about 4.4 square miles, and it has a maximum capacity of 300,000 acre-feet, although its normal storage level is 149,300 acre-feet.
The town of Somerfield, Pennsylvania, was abandoned, razed, and inundated when the reservoir was filled. The stone Great Crossings Bridge of the National Road, which crossed the Youghiogheny at Somerfield, is visible at extremely low water levels.
