Wildhorse Reservoir

Wildhorse Reservoir was constructed in 1937 and reconstructed in 1970. Its primary purpose is 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 Recreation Area and some private property surround the reservoir

Fishing Report

Wildhorse Reservoir is completely full and still spilling. Water temps are warming into the 60’s, which will begin to increase the smallmouth bass, catfish and wiper activity. Beach access remains limited due to the higher water levels. Trout will be feeding in the shallows in the early morning and evening, but moving to deeper water midday. Anglers should have luck with rooster-tails, spoons, or Rapalas. Anglers fishing from a boat could do well trolling flashers, spoons, and Rapalas, in shallower depths. Fly rodders may have success stripping wooly bugger or leech patterns, or fishing balanced leeches and midge patterns under an indicator.

Special Regulation: Black bass are catch and release only through June 30th.

Note: A die off of yellow perch (similar to what was observed in 2022 and 2023, but much less extensive) is occurring again this year. It is a bacterial infection and is mostly expressed in the yellow perch.

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. Wild Horse State Recreation Area has day use, camping, and a boat ramp and BLM has a day use and campground area near the north end of the reservoir. Wild Horse Resort has a motel, RV hookup, restaurant, bar, and a convenience store. Duck Valley Indian Reservation provides campsites and a boat launch.
