Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
Walleye are currently stocked in Washburn as frylings (when available) or fingerlings in alternate (even-numbered) years. Night electrofishing was conducted on September 24th, 2025, to assess young-of-the-year (YOY) Walleye abundance. The total sample time was 2 hours, which resulted in no YOY Walleye being captured. Previous catches ranged from 0 to 47.0 per hour. Walleye age 1 and older were captured at a rate of 6.5 per hour. These fish ranged in size from 7.4 to 15.8, with a mean length of 10.1 inches.
