Big Sandwash Reservoir

Fishing report

  • Rating: Good
  • Conditions: Fishing has improved because of the cooler water temperature and decreased water level. Smallmouth bass are abundant in the rocky points, but they have moved deeper and are a bit sluggish. For trout, trolling in the mornings and evenings has been effective. You may also want to try fishing the bottom with floating baits. Perch are plentiful, but are found in greater numbers in the north end of the reservoir. For smallmouth, try casting into the rocks with single-tail jigs or crawfish patterns and fishing deep. Bass and perch can be about 30 feet down. Wildlife managers are concerned about the presence of walleye in the reservoir. Please keep your limit of walleye.

  • Site description: Big Sandwash Reservoir is a mid elevation rainbow trout water located near Altamont and Bluebell Utah. The reservoir has recently been enlarged and because of construction, the old camping and angler access areas have been eliminated. A camping area is being developed below the new boat ramp. Angler access and restrooms are also being developed on the North Shore of the reservoir near the old highway. There are no camping or restroom facilities at the present time. There is a new boat ramp however, and the public can launch there. Expect excellent rainbow trout fishing for the next several years.
