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 (brook trout stocked 7 times here in 2026, moving water)

Drifted bait	single salmon egg or half a crawler under light split shot, rolled along the bottom
Small jerkbaits	floating minnows in the 2 to 3 inch class for the deeper bends
Waders or wet-wading boots	stocked stream fish stack in the obvious pools; getting to the next one is the edge

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