Current Conditions:
The Jefferson River will have fluctuating streamflows right now as the various weather patterns produce rain, snow, and warm weather. When the Jefferson runs at long term averages of around 1000 CFS at Twin Bridges, expect to fish fish well with both streamers and nymph rigs. The baetis are just showing up and will improve with the coming weeks. The fish are definitely concentrated in slower runs so find some good holding water before you fish. Rubber legs, eggs and pink copper johns are nice nymph choices. Big black streamers slow stripped along the bottom can produce some big browns for lucky anglers that are willing to endure some long slow stretches.
The Month Ahead:
The Jeff should produce decent fishing until run off begins in April or May. It is never a high numbers game due to lower trout counts but it is a nice location to get away and see few other anglers.
