Colorado Stream Update: The Roaring Fork is fishing well!

Current Conditions at Roaring Fork:

The Fork is giving up some great days on the water. Hopper-dropper rigs are finding some nice fish against the banks. Surveying seams and riffles through the day with nymph rigs should produce eats as well. In the afternoon there are opportunities for dry anglers. Small adams, and stimulators are a good place to start. Nymphs include Princes, worms, Barr's emergers, Two-bits, 20-inchers, and soft hackles- All in sizes 16-18.

This is one of the best times of year to be on the water! The flows on the Roaring Fork are great for both wade and float fishing.  The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 56-59 degrees and Slightly Off.
