Sand Hollow sits at the foot of Sand Mountain southeast of Hurricane, the reservoir water glowing the postcard red that the surrounding Navajo sandstone leaches into it. The lake is the largest in Washington County at 1,322 acres at full pool, and unlike Quail Creek twenty minutes to the west it is shallow, warm, and built around bass rather than trout. Two paved ramps — Westside and Sandpit — give boats access; the Sandpit side connects directly to the Sand Mountain OHV trail system, which is why every other rig in the parking lot is a side-by-side with a wakeboard tower.
Built for Bass, Not Trout
The reservoir filled in 2002, and the Utah Division of Wildlife Resources stocked it from the start as a warm-water fishery. Largemouth and smallmouth bass are the primary species, with bluegill, black crappie, and channel catfish filling out the panfish and catfish list. The state’s online stocking reports and the Southern Region hotspot guide both confirm there is no meaningful trout program here — surface temperatures climb past 80°F by late May and stay there through September, which is fatal to trout. Locals fish the rocky points and the submerged Navajo sandstone benches for smallmouth, the flooded brush and the rip-rap for largemouth, and the docks for crappie in spring.
The March Window Before Spring Break
Sand Hollow is a year-round fishery, but the unspoken local-favorite window is the second half of March. Water has warmed enough to bring bass to the shallows for pre-spawn, the spring-break crowd hasn’t fully arrived, and the wind that blows hardest in April is still mostly behaved. From mid-April through Labor Day the reservoir is busy — wakeboard boats running the long axis, jet-skis circling the islands, side-by-sides launching off the OHV beach. October through November cools back down for one more shoulder season before winter pulls the houseboat crowd off the water.
License, Fees, OHV Distinction
The Utah fishing license rule applies the same as at any state water — twelve and up, sold online through Utah Division of Wildlife Resources or at the state-park entrance booth. The state-park day-use fee is separate. Anyone riding the dunes pays an additional OHV permit; the OHV operation is a separate side of the park with its own check-in lane on the Sandpit road. Three reservable campgrounds — Westside, Sandpit, and the BLM-adjacent overflow — fill on summer weekends and on every spring-break Friday.
Sand Hollow Inside the 435
Sand Hollow and Quail Creek are the two anchor reservoirs of Washington County; locals run them like a doubleheader — Quail for trout in the cold end of the year, Sand Hollow for bass and bluegill once the water warms. The OHV scene at Sand Mountain is the highest concentration of side-by-side rentals in the country. The closest groceries, tackle, and gas are at the State Street end of Hurricane.
