Colorado Stream Update: Flows have started to rise! - Leave spawning fish alone

Current Conditions at Blue River Below Dillon:

More water has been moving down the Blue lately, and this should help the fishing. The best chance to find an eat is below the surface. Disco midges, top secrets, and RS2's are finding some fish. Mysis, small PTs and JuJu's are all good choices as well. Overall fishing has been rather slow, and a 'spot'n'stalk' mentality should be used. With that being said, sight fishing is by far your best way to increase eats but leave fish that are sitting on redds or paired up alone. Remember that depth is crucial when nymphing.

For a good chance at hooking a big fish try dead drifting mayfly patterns. Our guides suggest productive patterns like the Zebra Midge or Money Midge. Be sure and watch your step as the fish are beginning to spawn and eggs can be found throughout the river. Due to the spawning fish, fishing egg patterns can be quite productive.  The fishing is fair.  Overcast skies and 44-47 degree weather. The water temperature was between 36-39 degrees and Slightly Off.
