Cowan Lake State Park

1750 Osborn Road

Cowan Lake State Park offers a peaceful setting replete with scenic inlets laden with the American Lotus water lily. Swimming, fishing, sailing and canoeing are popular on the lake. Meandering trails through mature woodlands compliment the natural features of this scenic 1,075-acre park.


The Cowan Lake region was once a stronghold of the Miami and Shawnee Indians. After their defeat at the hands of General Anthony Wayne at the Battle of Fallen Timbers, the Indian threat subsided and settlement began here. In 1797, the first settler in the area, William Smalley, began clearing land for his home along the river which was later dammed to form Cowan Lake. Smalley had been captured by the Indians when he was a small child and was forced to live with them until he was twenty years old. He later fought in General Wayne's army and was recaptured, but luckily escaped with his life.

Cowan Creek was named for the area's first surveyor, John Cowan. A dam was completed across Cowan Creek in 1950, and in 1968, Cowan Lake was dedicated as a state park.

Beautiful park and lake. If you camp here please note the showerhouse have cold water showers only. A park employee told us of plans to renovate their facilities, which will include hot water in the bathrooms.

Terrible there was trash all over the beach. Big sign when you enter no garbage cans please take trash with you. So I am guessing we have cut park services so bad that they don't have money for trash cans or someone to empty them? I know eastfork has trash cans. Will never return would advise to go somewhere elese
