202-acre lake near Grant County. The lake tops out around 13 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Summit Lake draws 170 acres inside 3.4 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.7 mi end to end and 0.6 mi across at its widest. You'll find it in Grant County. For a second option, Blue Dog Lake lies 15 mi west.
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 4 to 13 ft game here, winter a 4 to 13 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (11 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (11 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: crappie in 2 to 8 ft. Midsummer fish sit out in 4 to 13 ft before dropping to 4 to 13 ft for winter. The spot to know is Deep basin, a deep basin in about 11 ft of water that rates prime for crappie in winter. Plan around early morning and the evening in the warm months. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.

Spring puts bluegill in skinny water — 1 to 6 ft is the zone. Warm water sends them out to 3 to 13 ft; cold water stacks them in 4 to 13 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring bluegill. Plan around early morning and the evening in the warm months. A small sponge spider (fly) or a micro tube jig covers the summer program.

The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 4 to 13 ft before dropping to 4 to 13 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

When the water first warms, walleye slide up into 3 to 13 ft. There's no big seasonal slide here — summer means 4 to 13 ft, winter 4 to 13 ft. If you only fish one area, make it Break off the point: a drop-off around 6 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

Come spring, look for black bullhead tight to the bank in 2 to 9 ft. They move out to 3 to 13 ft in summer and finish the year down in 4 to 13 ft. If you only fish one area, make it Deep basin: a deep basin around 11 ft that scores prime in winter. Best bite is after dark and the evening.
