Levi Meseberg, a former fishing guide in the Potholes, advises that trolling with a combination of hooks, colored plastic beads and a small metal blade is effective when it comes to fishing at the Potholes. Crankbaits are good for catching smallmouth bass, and leeches (live or artificial) work well among the reservoir's tangle of willow roots for largemouth bass.
There are 22 species of fish available at the Potholes Reservoir in Moses Lake, Grant County. The three major species are walleye, largemouth bass and smallmouth bass. Other game fish available are rainbow trout, crappie, yellow perch, bluegill and bullhead catfish.
Tri-cityherald.com advises that the reservoir's water is used to meet the local farmer's irrigation needs, so it is drawn down each summer. As the lake is always changing, a useful tactic is to move from one spot to another to find fish. Trolling with worm harnesses is the most effective way to chase Pothole walleyes.
Crab Creek Channel on the Potholes Reservoir is a hot spot for spring walleyes, according to "Washington Game & Fish Magazine." The Washington Department of Fish and Wildlife surveyed that almost 60 percent of walleyes on the Potholes average 15 inches and 1.6 pounds. Also a high percentage number of 4- to 8-pound lunkers can be found.
Another hot spot is the Seep Lakes Region, which is just below the O'Sullivan Dam. This area features 50 small fishing lakes that are abundant with walleye.
