I'm headed over to Hells Gate State Park in Lewiston, ID next month and was wondering if the river there is deep enough for my 18' Tiderunner? I was just thinking about bringing the boat along to do dome fishing, innertubing, and just playing. I just don't know the river there and if there are a bunch of rapids around then I won't bring the boat. I also have a 15' smokercraft that is smaller and easier in lower water. Does anyone know that area and is it worth brining the boat over or not. Thanks
