Big Sandwash Reservoir
Big Sandwash Reservoir is a mid-elevation, two-story fishery located near Upalco and Bluebell, Utah. The reservoir was recently enlarged, but the construction eliminated the old camping and angler access areas. There are restrooms and angler access points at the main boatramp on the dam and off of the Bluebell highway. The access turnoff is at 1000 N, but you should see the signs. Fishing should be excellent fishing for yellow perch, smallmouth bass and rainbow trout through 2018.
Latest fishing report
Water levels are extremely low. You cannot launch a boat at the reservoir. The water level is rising, but it is still one foot below the concrete boat ramp. Cooler water temperatures have improved trout fishing. (Last update 10-17-18)
