Jennings Run drops off the Allegheny Front to join Wills Creek at Corriganville, two miles above The Narrows. This run is about three and a half miles of nonstop terror. It has only one, continuous rapid, formed by ledges, boulders, gravel, tree trunks, and one demolished bridge. Eddies are rare, the water is muddy, and the scenery consists largely of views of the highway and nearby houses but the majestic wooded mountains rise high above on both sides, creating a beautiful backdrop. This is a great target for bored whitewater paddlers looking for a thrill and a challenge.
