Colorado Stream Update: The lower Blue has been fishing fair

Current Conditions at Blue River Below Dillon:

The Blue below Dillion is giving up some fish to the willing but overall, fishing remains so-so. Areas like shelves, soft riffles and pools will produce eats. There have been some PMDs still moving around, but most fish are being found on nymph rigs. Surveying soft seams, current breaks, and shelves is the way to go. Patterns like leeches, worms, and soft hackle flies are great point offerings. Trail a more selective pattern such as a Mysis or bling midge. Some fish have been picked up on rainbow warriors, and two-bits as well. Be sure to adjust depth accordingly!

This is one of the best times of year to be on the water! The leaves are changing and the weather has been cooling off.  The fishing is fair.  Clear skies and 60+ degree weather. The water temperature was between 56-59 degrees and Crystal Clear.
