Wildhorse Reservoir

Wildhorse Reservoir was constructed in 1937 and reconstructed in 1970. It’s primary purpose id for irrigation storage and, therefore, has large seasonal drawdowns. Most of the surrounding land is administered by the Bureau of Indian Affairs, but is leased to the Duck Valley Indian Reservation. Additionally, Wildhorse State Park and some private property surround the reservoir

Fishing Report

Surface water temperatures have moved into the mid to high 60’s and algae is growing and staining the water.  Anglers report good fishing for trout from boats or float tubes, while shore anglers report fair to good fishing in the mornings. Bass fishing is good and wipers have been showing up in the creel.  For trout, the same fly patterns continue to work as fly fishermen are having some success with black or wine colored leech patterns as well as wine or red chironomids. Damselflies and Mayflies are hatching so damselfly nymphs and dries are working as are Mayfly patterns such as Adams, blue winged olives and pale morning duns.  Wooly buggers, PT nymphs, gold ribbed hares ears and damsel fly nymphs are also producing a few fish.  For bait anglers try fishing an inflated worm a few feet off the bottom using a slip sinker in water that is eight to 12 feet deep.  Another option would be to roll some PowerBait to make a bell shape and fish it in a similar fashion to the inflated worm using a slip sinker and it will float up a couple of feet above the bottom.  Make sure to dip the PowerBait in the water for a few seconds after it is on the hook to “gel” it up so it doesn’t come off the hook when casting. For bass, dark colored soft plastic grubs and crankbaits are working.  Smallmouths are now legal to keep.  The limit is one bass 15 inches or longer.

Pertinent Information

At maximum capacity, the reservoir covers 2,830 acres, has a maximum depth of 70 feet, and an average depth of 40 feet. It has a coldwater, put-grow-take trout fishery and a self-sustaining warmwater fishery. Coldwater game species include rainbow, brown, bowcutt (rainbow x cutthroat hybrid), and tiger trout (brown x brook trout hybrid). Warmwater game species consists of smallmouth bass, largemouth bass, channel catfish, wipers (white bass x striper hybrid), and yellow perch. Harvest lengths of larger than 16 inches usually occur for rainbow trout and 19 inches for bowcutt trout. Wipers generally range from 14 to 25 inches, channel catfish from 14 to 28 inches, and black bass from 8 to 17 inches. Lures are best for trout from May through June and mid-September through October, and nightcrawlers, salmon eggs, corn, and Power Bait during December through February while ice fishing. Fly-fishing is popular in early spring and late fall. Shore and still fishing from a boat are successful; however, trolling is more productive in summer. Spring and early summer are best for bass using crankbaits and rubber worms, and for catfish using stink baits and liver. Use small jigs and worms for yellow perch. Wildhorse State Park has day use, camping, and a boat ramp and BLM has a day use and campground area near the north end of the reservoir. Wildhorse Resort has a motel, RV hookup, restaurant, bar, and a convenience store. Duck Valley Indian Reservation provides campsites and a boat launch.
