Allegheny River

Pennsylvania’s 2024 River of the year!

Named “La Belle Riviere” by French Explorers, the 325-mile Allegheny River is a spectacular waterway that cuts through Armstrong County. What was once used for transportation between Western Pennsylvania and New York is now a scenic waterway enjoyed by recreational boaters, paddlers, and fishermen. The Allegheny River is a scenic and popular waterway for both recreational boaters and seasoned sportsmen. Along the Allegheny, you’ll find great fishing opportunities. There are 47 different varieties of fish, including smallmouth bass, walleye, musky, and catfish! Whether fishing from a secluded bank or from the bows of their boats, anglers are sure to find plenty of exciting fishing action on the Allegheny. It’s also used for water skiing, swimming, and tubing — launch from any of our public launches or become a member of one of the private marinas to get in on all the action.

There are also six centrally located picnic areas maintained by the Corps that provide picnic tables and charcoal grills.

Keystone Lake

As the largest lake in Armstrong County, Keystone Lake covers 850 acres and stretches 5.5 miles. While the deepest part of the lake is 90 feet deep, the lake also features shallows and wetlands. Owned and operated by Reliant Energy as a cooling water supply for Keystone Power Plant, the lake and surrounding area are open for public use.

The lake has two formal boat launches with large parking areas: NuMine (north shore) off of Route 85 at White Oak Road and Atwood (south shore) off of Route 210 in the borough of Atwood. There are also several primitive access areas around the lake.

Keystone Lake provides an excellent warm water fishery with large and smallmouth bass, walleye, musky, perch, crappies, bluegills, sunfish, pumpkin heads, and trout (stocked). As a trophy bass lake, several professional tournaments have been held here.

Several thousand acres surrounding the lake are open to hunting, where PA Game Commission laws and regulations apply. When winter weather conditions permit it, the lake is also a wonderful place for ice fishing.
