Copper River confluence

"The winds at the Copper river confluence and the strength of the river can catch you off guard. The locals said that the wind at the confluence is a pretty standard phenomena at the confluence. In addition to the wind, with the increase in volume comes some serious powerful boils in certain spots. One in particular was on the corner RR of the Copper confluence, I'm sure there tons. Because the weather was incredible, and the river was pretty calm the last few days we were not in our drysuits, next we will be!. WARNING: Boils at the Copper Confluence could easily flip a 16 foot boat and if one is not in their drysuits, they would assureadly be in a fight for their life because of the strength, and temperature of the water."  (Moenkopi, 2011)
