Flows are great at 170 cfs. Primary hatches consist of blue wings, pmds, and caddis. The caddis fishing has been best in the afternoon. Leeches and streamers have been finding fish in the morning. Dry fly opportunities are starting to ramp up with fish looking up. Terrestrials (ants and beetles mostly) are finding fish as well. As usual, nymphing remains the most productive.
Have fun and stop by TRR Outfitters in Eagle or call (208) 939-6065 to stock up on some flies, purchase your Owyhee fishing license, or book a guided fishing trip.
