Contact the people at three rivers resort and ask,they do it commercially. Ask for Vito, he is the guy in charge of river clean-up. Be very careful going under the very low bridge, and stay right on the run thru, left side is usually not good. This is my favorite section because of all the fishing weirs with small drops. There is one real decent 5' to 6' drop in there with a big hole at the bottom of rapid, but it goes. We will be coming up Sunday for the race and running it. We usually always run from Slot to Five Mile Bridge
