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 (trout stocked 1 time here in 2026, stillwater)
| Ultralight spinning rod | 6 to 7 ft ultralight, 4 lb line; long casts from the bank |
| Dough bait rigs | floating dough bait 18 inches above a small egg sinker; hatchery fish know the smell |
| Casting spoons | 1/8 to 1/4 oz in fluorescent or metallic; count down until you find the depth |
Suggestions follow from what the state actually stocks here and what kind of water it is, nothing else. No sponsored placements.
