Colorado Stream Update: Streamers are hot!

Current Conditions at Big Thompson:

With Fall on the door-step fish are willing to be slightly more opportunistic. There has been some great streamer action as of late. Small leeches, buggers, and minnows have been moving some great fish. A light nymph rig has been producing a lot of eats. Be sure you are fishing the right depth. Two-bits, PTs, and RS2's are a good place to start. Stimis, and Amy's ants are good for towing a deep nymph. Focus efforts towards side seems, and major current breaks but look for fish to move into riffles throughout the day.

Black streamers have been producing vicious strikes. The water is low and clear and fly fishing reports have been excellent.  The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 56-59 degrees and Crystal Clear.
