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 2 times here in 2026, moving water)

Light spinning rod 5 to 6.5 ft light or ultralight; short rods cast under branches
Inline spinners 1/16 to 1/8 oz silver or gold; swing them across the current seams
Drifted bait single salmon egg or half a crawler under light split shot, rolled along the bottom

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