Seneca Lake, also known as Senecaville Lake, is one of Ohio's top boating and outdoor attractions. Situated in Guernsey County and Noble counties just south of Cambridge, it covers 3,550 acres framed by a picturesque shoreline 45 miles long.
Managed by the Muskingum Watershed Conservancy District, the lake was constructed by the US Army Corps of Engineers in 1938 for flood reduction and water conservation. Popular demand has come to define Seneca Lake as an outdoor recreational paradise.
Seneca Lake and accompanying Seneca Lake Park are easily accessible. Boating, fishing, camping, hiking, biking, hunting, swimming and more are among the reasons Seneca Lake is so popular. The park supports a full schedule of activities and events each year from Memorial Day through Labor Day.
