Current Report

Water flows are at 4,000 cfs and the water temperature is 44 degrees. The water clarity is improving. Brown trout are spawning and both nymph and streamer fishing is productive. Fish are eating sowbugs, scuds, Baetis nymph patterns, midge pupa, and aquatic worms. A light fly/dark fly combination (yes, a two-fly rig) works well for streamer fishing.
