The Enterprise Reservoirs sit about ten miles west of the town of Enterprise on Forest Road 009, two reservoirs in series — Lower at roughly 280 acres, Upper at roughly 50 — separated by a short stretch of Shoal Creek. They are USFS Dixie National Forest waters with an irrigation operating layer underneath, and the country up here is rolling pinyon-juniper at about 5,800 feet, more forested than the desert reservoirs and quieter than anything within an hour of St. George. From St. George it is fifty miles up UT-18 through Veyo, Central, and Enterprise, then the Forest Road climb west to the dams.
Lower Is the Big One, Upper Is the Quiet One
The Utah Division of Wildlife Resources stocks both reservoirs with rainbow trout, with the heavier stocking concentrated at Lower Enterprise where the surface area and the depth produce the better trout fishery. Smallmouth bass are present at Lower as a secondary species. Upper Enterprise is smaller, shallower, and gets less foot and trailer traffic — anglers who hand-launch a kayak or float tube and fish the inlet and the dam typically have the water to themselves. The DWR stocking-report tool is the canonical source for the calendar in any given year. Both reservoirs sit at elevation high enough that surface temperatures stay fishable through the summer, unlike the Washington County desert reservoirs.
Honeycomb Rocks and the Camping Layer
Honeycomb Rocks Campground sits between the two reservoirs along Shoal Creek and is the standard base for a fishing weekend out here. It is reservable through Recreation.gov, has potable water and vault toilets, and books out for holiday weekends. The campground name comes from the weathered volcanic-tuff outcrops that frame the loop. Primitive dispersed camping is also available off the Forest Road; the standard USFS dispersed rules apply (fourteen-day stay, leave-no-trace, fire restrictions seasonal).
License, Fees, Practical Bits
The Utah fishing license rule applies — twelve and up, sold online through the Utah Division of Wildlife Resources or at sporting-goods counters before leaving St. George or Cedar City. The Honeycomb Rocks site fee covers camping; there is no separate state-park day-use fee at the reservoirs themselves. Cell service is intermittent. The closest fuel and full grocery are back in Enterprise (small) or Cedar City; plan the cooler accordingly.
Enterprise Reservoirs Inside the 435
The Enterprise Reservoirs are part of the cold-and-cool-water reservoir circuit that 435 anglers run when desert water gets too warm — Pine Valley Reservoir up top, Baker mid-elevation, Enterprise out west, Yankee Meadow and Navajo Lake on the eastern Iron County reach. The drive out passes through some of the quietest farm country in the 435; the loop home through Pine Valley and Veyo doubles as a scenic route in autumn when the aspens turn on the mountain.
