About

Dam releases from Bear Swamp Pumped Storage Station drive the Deerfield River through 65 miles of Franklin County whitewater, averaging 1400 CFS with optimal flows between 400–1500. The Dryway section delivers Class III–IV expert runs when Bear Swamp opens the gates, while Fife Brook offers more manageable Class II–III water on scheduled releases. Below Charlemont, the river mellows to Class I–II through the scenic valley toward Shelburne Falls. Commercial outfitters Zoar Outdoor and Crab Apple Whitewater run trips on the dam-controlled sections, timing launches to the hydroelectric schedule. The Berkshire Natural Resources Council and American Whitewater maintain stewardship agreements that balance power generation with recreational access. USGS gauge 01170000 tracks the releases that make or break a Dryway run — this is not a river that flows naturally, and paddlers who ignore the generation schedule find themselves scraping through bony shallows or facing unpredictable surges.
