Banks Lake, a sprawling reservoir near Grand Coulee, WA, stands out as one of Washington’s most versatile fishing destinations. Stretching over 27 miles, this body of water is home to a healthy population of walleye, smallmouth bass, rainbow trout, and yellow perch. Its diverse structure—featuring rocky drop-offs, submerged islands, and weed beds—offers something for every type of angler.

Spring and early summer are peak times for walleye, especially near rocky points and submerged humps. Jigging, trolling bottom bouncers, or running crankbaits near structure consistently produces results. Smallmouth bass flourish in warm months, thriving along the lake’s rocky banks and boulder-strewn flats. Anglers enjoy steady bass action using soft plastics, jerkbaits, or spinnerbaits.

Rainbow trout are a reliable target in the cooler months, with trolling and bank fishing both effective methods. PowerBait and worms perform well from shore, while boaters can use spoons or wedding rings to cover water. While yellow perch don’t get the same spotlight, they’re plentiful in shallower, vegetated areas.

Shore and boat access are excellent, with Steamboat Rock State Park offering ideal amenities for anglers and families alike. Banks Lake combines quality fishing with high desert scenery, making it an ideal year-round destination. Regulations vary by species, so always check with WDFW before casting off.
