Big Sandwash Reservoir

Fishing report

  • Rating: Good
  • Conditions: Be careful. The reservoir is filling, and the edges can have thin ice and open water. Also, ice near the inlet is not as thick and has an irregular pattern because of currents. Anglers have been fishing the northern bays and are catching perch and a few rainbows. Try either the top 10 feet or the bottom 10 if fishing for trout. Perch are mainly on the bottom, but there are schools of larger fish moving through, and they can be at any depth, including within a few feet of the surface. Try a small, brightly colored jig, jigging spoon or fly tipped with a worm, mealworm or soft artificial bait. Perch are plentiful but mostly small and have been found in greater numbers in the northern end of the reservoir, 25–30 feet deep. The presence of walleye in the reservoir has caused some concern for managers.

  • 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.
