Colorado Stream Update: Run-off is here and summer is around the corner

Current Conditions at Gunnison:

Flows have been rising daily on the Gunny and this can be expected until run-off subsides. With that being said, water is high and off color. Fish are holding in soft seems and pockets. A nymph set-up is the way to go. San juan worms, Girdles and leeches are great choices with high water. Be sure to get those flies down into feeding lanes, one more split-shot can make a huge difference. Don't be afraid to swing a streamer! Some trout are still finishing their spawn so please be respectful

For best results try fishing heavily weighted stonefly nymphs. The weather has been warm and the water is beginning to rise. The water on Colorado‚Äôs favorite freestone streams has been running very high! Steamers are a fantastic way to move large trout during the higher water.   The fishing is good.  Overcast skies and 48-51 degree weather. The water temperature was between 36-39 degrees and Stained.
