Description - The area comprising Harrison Lake State Park was at one time part of a vast wetland. This mysterious area contained towering trees, soggy black soil and was a haven for the swamp rattlesnake (or massassauga, as it is also known). Very little remains of that once great swamp, but the park still harbors unique natural features associated with wetlands.

Harrison Lake State Park
In 1941, a dam over Mill Creek was completed and Harrison Lake was created. The lake and surrounding area were maintained primarily for hunting and fishing purposes until 1950 when Harrison Lake was established as a state park and development for additional recreational usage began.
- The campground at Harrison Lake State Park has 193 campsites of which 126 have electricity. The campground features showers, flush toilets, a dump station and sites designated for campers with pets. A group camp area with a 50-person capacity is available for organized youth groups on a reservation basis. Three Rent-A-Camp sites consisting of a tent, sheltered picnic table, cooler, cook stove and other equipment can be rented during the summer months by reservation.
