No recent survey rating.
Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear, so the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, only presence and size are listed. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey.
How to fish Crystal Lake through the year
Walleye
- Spring
- Walleye are shallow, on and just off the spawning flats and the first green weeds. In 1.9 ft of visibility, they sit shallower than you think.
- Early summer
- Walleye are setting up on the outside weed edge, points and shallow structure.
- Summer
- Walleye are working the weed edge, points and any wind-blown structure. With 100% of this lake 15 ft or shallower, the weed edge is the main event.
- Fall
- Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows. A 8-ft bowl cools fast, so the fall window comes early here.
Northern pike
- Spring
- Pike are in the shallow bays and along new weed growth. In 1.9 ft of visibility, they sit shallower than you think.
- Early summer
- Pike are on the outside weed edge and points.
- Summer
- Pike are on the deep weed edge and points near the coolest water they can find. With 100% of this lake 15 ft or shallower, the weed edge is the main event.
- Fall
- Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops. A 8-ft bowl cools fast, so the fall window comes early here.
