Gear for this water

It has been a while since the trucks came. The holdovers have spread out and wised up; downsize and fish natural.

For the trout (rainbow trout stocked 8 times here in 2026, stillwater)

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
Dough bait rigs floating dough bait 18 inches above a small egg sinker; hatchery fish know the smell

Suggestions follow from what the state actually stocks here and what kind of water it is, nothing else. No sponsored placements.
