History
Senecaville Dam was built in 1937 by the U.S. Army Corps of Engineers as part of the Muskingum Watershed Conservancy District's flood control and water conservation project. The Seneca Fork of Wills Creek valley was dammed to create a flood control and water conservation reservoir. The reservoir presently forms a conservation pool for flood control, recreation, fish and wildlife, and for the maintenance of normal downstream flows during dry periods.
Senecaville Dam
The Senecaville Dam is located at the northwest end of the lake near the village of Senecaville. Originally completed in 1937, the structure was modified in 1982. The dam is made of earthen construction and measures 49 feet (15 m) high by 2,350 feet (720 m) long. The core is homogeneous earth with a foundation of rock and soil. The Dam is separated into two embankment sections, North and South, by a rock knoll, through which the outlet works is located and across a low dike constructed section. Maximum discharge is 11400 cubic feet per second. Its capacity is 88,500 acre feet (109,200,000 m3). Normal storage is 43,500 acre feet (53,700,000 m3). It drains an area of 118 square miles (310 km2).
