The U.S. Army Corps of Engineers constructed a rolled earth dam to form Tappan Lake. The impressive structure has a maximum height of 52 feet and a top length of 1,550 feet. The lake soon became a top outdoor recreation spot for fishing, boating, and camping.
Tappan Lake Park provides over 500 campsites that include electric and full hookup sites. Primitive and group campsites are a bit more rugged. For those not so willing to rough it 10 cabins are available.
Fishing is a regular occurrence on the lake with several species providing excellent prospects.
