To get to the hatchery, take I-77 south off of I-70, then take OH-313 east for about six miles and turn right on Seneca Dam Road; the hatchery is on the right about a half-mile.

Senecaville State Fish Hatchery is located on over 120 acres in southern Guernsey County below the dam of Seneca Lake. This facility was acquired from the U.S. Fish and Wildlife Service in 1987. The hatchery has 37 ponds containing a total of 37 water acres. The facility also has two outdoor raceways and 18 indoor rearing troughs. Water is supplied by Seneca Lake, which can deliver 2,000 gallons per minute. This water supply allows the hatchery to raise saugeye, walleye, hybrid striped bass, and channel catfish. Senecaville State Fish Hatchery is the main facility for saugeye and hybrid striped bass production. Fry produced at this facility are raised on-site and also shipped to other state hatcheries to be raised to stocking size. Saugeye and walleye production begins in early spring, and hybrid striped bass production starts in late spring with egg collection and fertilization at the hatchery. This hatchery is also the main production facility for channel catfish. Channel catfish production starts in the summer using breeding adults kept at the hatchery. These fry are raised on-site and also shipped to other state hatcheries to be raised to stocking size.

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 the 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.
