Was wondering what is considered wadable waters as far as CFS? Does CFS stand for Cubic Feet per Second? If the Yakima is say for example 500CFS and the Cowlitz is 500FS, does that mean they are at the same water level, wadable or not wadable. I've always been confused on how to read the river water level charts. What is the best web site to check rivers in our state,area,etc? UNNO Thanks again!
