Seneca Lake is in eastern Ohio, mostly in Noble County, with a small northern portion in Guernsey County. The dam is located 2 miles east of Senecaville on OH-313 and 12 miles southeast of Cambridge via I-77 and OH-313.
Seneca Lake dam was built across the valley of Seneca Fork of Wills Creek by the U.S. Army Corps of Engineers in 1938 for flood control and recreation. It was opened to fishing in 1940, but due to highway relocation the lake did not reach conservation pool until March 1942.
The lake is in the Muskingum Watershed Conservancy District’s (MWCD) chain of lakes and all boating, swimming, camping, and picnicking is under MWCD control. Seneca Lake Park is operated by the MWCD. The Division of Wildlife annually leases public fishing and hunting rights on MWCD lakes and lands. Seneca Lake, the largest of the MWCD lakes, has 3,509 surface acres of water and 45 miles of shoreline.
