You can follow an ATV trail for a couple hundred yards, then you'll want to turn right, in a direction directly away from the road - perpendicular to it, if you will. A couple more hundred yards through the woods and you'll go down a steep bank into a small bog, and then you'll begin to hear the river. Follow the sound towards the rushing water and you'll come out on a really nice set of bolders in the river, leading into a long, deep pool.
I reached the pool and was trying to decide how to start fishing as I watched the water. Within a few minutes, I spotted a rise, then another. I had a size 16 Blue Wing Olive on, so I made some false casts, targeting the rise. Soon I had a take and a solid hookup. A few moments later a small landlocked salmon was in my net. Hard to complain about that.
