Every single thing SCN said above is dead on the money. 20 years ago I flyfished that river exclusively and those were the types of flies and exactly how I did it. I loved fishing in the dead of winter because the fishing was good and the crowds were non existent. Down in that horse shoe below the dam in the first bend was always a favorite of mine. If you want first crack at it then be there at daylight. Most of the other fisherman will not be there till later. There used to be some great access points that farmers would let you walk across their land to fish but unfortunately a few bad experiences from a a few bad people closed it off to everyone.
