Lake Roosevelt, WA Fishing Report & Live Conditions
Lake Roosevelt, WA fishing report
Lake Roosevelt, the reservoir behind Grand Coulee Dam, offers a diverse fishery that shifts significantly through the year. Walleye are the bread-and-butter species, drawing serious anglers from across the region. Kokanee run strong through summer and into fall, staging near deeper, cooler water as temperatures climb. Rainbow trout are most active in spring and again in fall when surface temps cool into that productive 50-65 degree range, and they can be surprisingly large given the forage base this impoundment provides.
For walleye, target rocky points, submerged structure, and transition edges where gravel meets soft bottom, using jig-and-minnow combinations or bottom bouncers with crawler harnesses — dawn and dusk bites are most reliable. Kokanee respond well to small dodger-and-wedding-ring setups trolled at depth; find the thermocline and you find the fish. Trout cruise shallower during cooler months and can be intercepted with spinners or bait near tributary inflows, especially when spring runoff draws them to feeding lanes.
