Gear for this water
Stocked within the last three weeks: fish are still bunched near the release points and keyed on familiar smells.
For the trout (rainbow trout stocked 6 times here in 2026, stillwater)
| Small crankbaits | trout-pattern cranks trolled or slow-retrieved off points |
| Slip bobber and jig | 1/32 oz marabou jig or waxworm suspended at cruising depth |
| Ultralight spinning rod | 6 to 7 ft ultralight, 4 lb line; long casts from the bank |
For the walleye (walleye stocked 1 time here in 2026, stillwater)
| Crawler harness | slow-trolled over flats and breaks once water warms |
| Medium spinning rod | 6.5 to 7 ft medium, 8 lb line; sensitivity beats power here |
| Jigging raps and blade baits | vertical over deep structure in the cold months |
Suggestions follow from what the state actually stocks here and what kind of water it is, nothing else. No sponsored placements.
