Current Report

 Water flows are at 4,000 cfs and the water temperature is 40 degrees. The water clarity is perfect and the fishing is good. Throw full sinking lines if you’re a streamer fisherman. A light fly/dark fly combination (yes, a two-fly rig) works well. Fish are eating sowbugs, scuds, Baetis nymph patterns, midge pupa, and aquatic worms. There are some midges and a few Baetis around.
