Kennebec River High Water Rafting: Maine’s Biggest Whitewater Experience

During a turbine test, Brookfield Power tests their generating turbines by releasing the maximum amount of water possible from Harris Station Dam. 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. They let us know these dates ahead of time so we can let YOU know! If you love whitewater action, you will want to be on one of these special Turbine Test release trips–only 4 per season!

Your Day Rafting Kennebec River High Water

Morning Check in

Whitewater rafting trips on the Kennebec River gather at The Forks Adventure Resort at 7:45am for a safety orientation, paddling instructions, and to gear up before the short ride to Harris Station Dam.

Your River Trip

Upon arrival at the Dam, your Registered Maine Whitewater Guide will lead you and your crew into the granite walls of the upper Kennebec River gorge. 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 a brief stop for a snack, into the fast-moving lower section surrounded by forests and wildlife. Enjoy incredible scenery, exciting rapids and plenty of opportunities to float in the water and see wildlife such as eagles and osprey diving for fish!

Post River Trip – Including Lunch

Northern Outdoors’ rafting trip takeout is only a few miles up the road from our resort. After a short ride to The Forks Adventure Resort, you’ll enjoy a classic grilled lunch and microbrew at the Kennebec River Pub & Brewery including steak, salmon, chicken, or veggie burger grilled over a hardwood fire, accompanied by stir-fried rice, salad, dessert, and beverages. After lunch the guides put on a slideshow of photos and video of you conquering the whitewater — grab a craft beer, kick back, and get ready to laugh!
