River Description
A fine float trip from below the Hinckley Dam to the confluence with the Kettle River (with another 1.6 miles paddle-out on that to the public landing on Hwy.48). There appear to be numerous areas of shoals which should create fine riffles and rips, perhaps waves and even legitimate rapids at good flows.
We have no first-hand information nor reports regarding this run. Have you paddled it? Help out your fellow boaters with a comment or report! (Photos or videos are a bonus!)
