The Washington Department of Fish & Wildlife has conducted Fall Walleye Index Netting Surveys (FWIN) on Banks Lake since 2002. The most recent survey occurred October 13–16, 2025. The department set and retrieved 48 gill nets distributed across all major lake basins and depth strata to provide lake-wide coverage. They caught an average of 4 Walleye/net, which was nearly equal to the long-term average of 4.4 Walleye/net. The average length of Walleye caught was 16.3 inches with the largest fish being 26.2 inches. Most fish were between 12–16 inches (38.8%) and 16–20 inches (36.7%). More 16–20-inch fish were caught in 2025 than in 2022. This could mean that Walleye anglers might expect to catch more fish between 20–24 inches in 2026, as well as more fish in the 16–20-inch size class in 2027. This report has made me excited about fishing for walleye on Banks Lake. The month of August has treated my very well over the years. Last year in August I got a chance to fish with Nate Stully of Stully’s Guide Service, and we got near limits of very nice walleye.
