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 walleye (walleye stocked 1 time here in 2026, stillwater)

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
Jig and minnow	1/8 to 1/4 oz round jigs tipped live or plastic; drag the bottom slowly

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