Authorized by the Flood Control Acts of 1936 and 1938, Tionesta Lake is one of 16 flood control projects in the Pittsburgh District. Tionesta is a key link in a system of flood control project for the Allegheny and upper Ohio Rivers. Since its completion in 1940, Tionesta has prevented over $570 million in flood damage. The project’s flood control capabilities were dramatically demonstrated during the 1972 flooding resulting from Tropical Storm Agnes when over $62 million in damages were prevented by Tionesta alone. 

Recreation, Events, Facilities & Activities


Winding its way through the rugged hills of northwestern Pennsylvania, Tionesta Lake offers a unique setting for a diversity of outdoor recreational opportunities. The U.S. Army Corps of Engineers invites you to visit the project and discover Tionesta's delightful lake and the natural beauty of the surrounding forest.

For those looking for a memorable outdoor experience, Tionesta offers a mix of beautiful scenery and recreational activities that will not soon be forgotten. Outdoor enthusiasts can enjoy boating, camping, hunting, fishing, hiking, water-skiing, picnicking, sightseeing and much more. There are no parking fees. 

Fishermen have found the variety of fishing waters in the area enticing and productive. The clear mountain streams, placid lake and glistening Allegheny River have yielded many fine catches of trout, muskie, walleye, bass and panfish.

The lake and its miles of unspoiled shoreline offer unlimited opportunities for water-based recreation. Watercraft of all types and sizes can be found on Tionesta Lake, from powerboats of unlimited horsepower with water skiers in tow, to sleek canoes and small fishing boats plying the inlets, coves and backwater areas of the lake. Easy access to the water is provided by boat launches at either end of the lake with ample trailer parking available.

Home to a remarkable variety of wildlife, Tionesta has claim as one of Pennsylvania's best big game regions. Hunters will find deer in abundance as well as bear, turkey and small game. Part of the pleasure of hunting at Tionesta is experiencing the quiet, rejuvenating forest.

Campers will find a welcome change of pace from everyday urban life at one of Tionesta's many tree-shaded campsites. Camping facilities range from rustic in nature, located at lakeside and accessible only by boat, to sites equipped with hot showers and full hook-ups.

If out sightseeing for the day, why not stop at Tionesta and enjoy a leisurely picnic with family or friends or perhaps walk on one of the self-guided nature trails?  There are also several scenic overlooks that provide exciting vistas of the lake and forested hillsides. An especially scenic time for sightseeing at Tionesta Lake is in the autumn when the splendor of the fall foliage is at its peak.

Life Jacket Loaner Program for Kids

The Boat/U.S. Foundation for Boating Safety has funded a Life Jacket Loaner Program for kids at Tionesta Lake. Fifteen life jackets in three sizes for children are available:  infant, child and youth. The U.S. Coast Guard requires recreational boats to have a wearable life jacket on board for each passenger, but life jackets suitable for children are not always available. In addition, at Tionesta Lake and other Corps of Engineers lakes in the Pittsburgh District, it is required that children under 13 years of age wear a life jacket while boating. Children are especially at risk on and near the water. A properly sized life jacket can be the difference between life and death for a small child. A boater merely signs out the jacket(s) and returns it at the end of the day. Please call the Park Office to make arrangements.

Information Center

The Information Center located on top of the Dam, is open on Saturdays, Sundays and holidays during the summer months. The hours are 12:30 p.m. to 3:30 p.m.
