Tohickon Creek is one of the Mid-Atlantic's most famous dam-release whitewater runs, delivering Class II–IV creek-style paddling through a scenic gorge in Ralph Stover State Park. Twice-yearly scheduled releases from Lake Nockamixon (usually March and November) draw hundreds of boaters from NY, NJ, MD, and PA to one of the few reliable whitewater runs in the eastern seaboard.
