Fishing Report

Fishing has been good at Topaz as we continue to stock the lake regularly. Anglers from shore are using powerbait and crawlers off the bottom. Now is a good time to find the larger trout closer to shore.

Pertinent Information

Topaz Lake is relatively large with a surface area of 2,410 acres, a length of 3.5 miles, a width of 1.5 miles, and maximum depth of 92 feet. Rainbow trout is the dominant sport fish, but bowcutt trout, brown trout, and occasionally tiger trout are stocked. Smallmouth bass and to a lesser degree largemouth bass are also popular for angling. Boaters should use a fish finder to determine the depth fish are occupying, which is usually in the upper 20 feet of the water column, and troll Rapalas or nightcrawlers with flashers to catch trout. Shore anglers do best with Power Bait or nightcrawlers and cast out as far as possible. The average size of rainbow trout is usually around 12 inches, but they commonly range from 10 to 18 inches. Several five pound or larger fish are caught every year. Black bass are commonly caught with rubber worms, jigs, and crankbaits along the shoreline or off deeper points. Most of the property around the lake is open to the public. Only portions of the west shore in Nevada and California and the far south end of the lake in California are private property. Boat launching is available at Topaz Marina and Douglas County Park. Douglas County Park provides camping, electrical hook-ups, bathrooms, picnic tables, playground, and a fish cleaning station. Topaz Marina has fishing boat rentals, boat slips, and food and drinks.
