Jennings Randolph Lake · Mid-Atlantic Tailwater

The North Branch Potomac is a cold-tailwater trout fishery below Jennings Randolph Lake, transformed from an acid-mine-dead river into one of the finest wild rainbow and brown trout streams in the Mid-Atlantic. Scheduled whitewater releases from the dam create classic Class II–III paddling, and the river supports trophy trout for 25 miles below the lake.

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and trip sections may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level. If you spot an error, use the Improve This River button at the top of the page — your local knowledge is what makes this atlas accurate.
