Owyhee River, East Fork

The East Fork of the Owyhee River is the tailwater below Wildhorse Dam which was built in 1937.

Type of water
Fishing Report

With the lack of snow, stream flows are dropping quickly and many are now fishable. With the poor snowpack and the unusually warm spring, anglers should take advantage of early summer conditions while they can. Expect very low stream flows later this summer. Flows in the upper stretch of the river have increased as water is being drawn out for irrigation. Fishing has been good using common nymphs such as copper Johns, hares ears and PT nymphs. Caddis flies and Mayflies are starting to hatch so anglers may want to try emergers and dries. Swinging small buggers and streamers should also be good. Spin fishermen should use small gold spinners. As of June 24, the East Fork of the Owyhee below the dam was flowing at 91.8 cfs while near Mountain City the gauging station was flowing at 115 cfs.


Pertinent Information

The East Fork of the Owyhee River is subject to large flow swings ranging from about 15 cfs to 1500 cfs in the spring. The first 1/2 to 3/4 of a mile below the dam the fish are mostly reservoir fish and larger in size. Below that wild rainbows predominate averaging 8 to 15 inches in size. There are approximately 6 to 7miles of fishable stream in the canyon below the dam. Once the canyon starts to widen, private land becomes an issue.
