Rivers & Lakes

Allegheny River

More than 60 miles of the roughly 325-mile-long Allegheny River traverses Armstrong County and provides an outdoor oasis for boating enthusiasts, anglers, and nature lovers. A series of locks and dams constructed in the early 20th century make the river navigable. Learn more about the locks and dams and find a lock operation schedule on Allegheny River Development Corporation’s website, alleghenyriverdevelopment.org.

Crooked Creek Lake

Nestled among the rolling hills of western Pennsylvania, Crooked Creek Lake is open for year-round outdoor recreation, including boating, waterskiing, swimming, fishing, hiking, birdwatching, and disc golf. The Crooked Creek Lake Visitor Information Center (VIC) has seasonal operating hours and offers group tours. Contact the VIC at 724-763-3161.

Keystone Lake

As the largest lake in Armstrong County, Keystone Lake covers 850 acres and stretches 5.5 miles. 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 area is controlled by the PA Fish & Boat Commission, which means all of their rules and regulations are in effect. Swimming is prohibited, but boats up to 20 HP are permitted.

Kiskiminetas River

The Kiskiminetas River — known locally as the Kiski — is a 27-mile-long tributary of the Allegheny River that forms the southern border of Armstrong County. It is a popular destination for canoeing, kayaking, and fishing. As part of the former Pennsylvania Main Line Canal, visitors can also find historical sites along the shore dating back to the early 1800s.

Mahoning Creek Lake

Situated along steep-sided valleys and wooded hillsides, Mahoning Creek Lake is a peaceful and relaxed atmosphere for kayakers, canoeists, and fishermen alike. Located near the dam is a shaded picnic area with restrooms, grills, picnic tables, a playground, and walking trails. Swimming is not permitted. You can schedule a tour of Mahoning Dam by calling 814-257-8811.
