With just four special releases each year, the Kennebec River Turbine Test dates are the real deal.  HIGH water, HUGE waves, and TONS OF FUN… don’t miss the highest volume whitewater rafting in Maine!

Are You Ready to Tackle Maine’s Biggest White Water Releases?


If you love whitewater action, you will want to be on one of these special Turbine Test release trips–only 4 per season! Kennebec Turbine Test rafting trips enjoy 8,000+ cubic feet per second (cfs) water flows, which is nearly DOUBLE the Kennebec River’s normal whitewater rafting release volume. During a turbine test, Brookfield Power tests their generating turbines by releasing the maximum amount of water possible from Harris Station Dam.


This aggressive, high-adventure whitewater rafting trip races through the beautiful Upper Kennebec Gorge with non-stop action and huge waves. The Kennebec broadens after lunch, into the fast-moving lower section surrounded by forests and wildlife. Enjoy incredible scenery, exciting rapids and plenty of opportunities to play and see wildlife such as eagles and osprey diving for fish! The river put-in is only a 30-minute bus ride from the check-in and the trip ends just a short ride from our Northern Outdoors Adventure Resort, where you’ll enjoy a classic grilled lunch and microbrew at the Kennebec River Pub & Brewery.
