The water out of the Wildhorse just a trickle and fishing is difficult in much of the stream. Some of the larger pools have been productive for trout, with those closer to the dam having reservoir fish while those further down the canyon producing wild trout in the 10 to 15 inch size. Anglers report good fishing near the USFS Wildhorse Crossing Campground with dries. Grass hoppers, caddis patterns and chubby Chernobyl ant patterns, as well as other dry flies have been effective. Spin fishermen should use small gold spinners or dark spinners with contrasting light colors. As of September 30, the East Fork of the Owyhee below the dam was flowing at 2.78 cfs while at the gauging station in Mountain City it is flowing at 4.67 cfs.
