DNR fish survey, 2025
| Species | Gear | Catch per net | Total catch | Avg lb |
|---|---|---|---|---|
| Walleye | Fall electrofishing | 23.33 | 35 | 0.00 |
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.
A survey targeting age-0 Walleye was conducted at Tetonka Lake on 29 October 2025 using 1 hour 30 minutes of standard boat electrofishing. A total of 35 age-0 Walleyes were sampled for a catch rate of 23.3/hour on-time. Catch rates during fry-stocked years (n = 15) have averaged 57.7/hour on-time while non-stocked years (n = 7) have averaged 64.9/hour on-time. The mean length in 2025 was 8.1 inches. The robust catch rates during non-stocked years suggests natural reproduction plays an important role in Walleye recruitment in Tetonka Lake.
