I have fished the Snake for the last twenty years. There is a lot of boat launches all along the river from the confluence of the Clearwater on up to the Heller bar. The only launch that is unusable is the one at Asotin, it has filled with sand. My favorite spot to launch is just past the town of Asotin on the left, no dock so pull your boat up on the beach. You can fish up river past Three mile (line up the channel markers) or run down towards Clarkston. This is a catch and release fishery as they are not worth eating. I have caught fish up to 20# on plugs, bait, jigs/bobbers and spoons. Lots of fun! Dress warm! Follow all the rules both Idaho and Washington wardens are working this area.
