613-acre lake near Lake County. The lake tops out around 25 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here is how the season plays out for each species, straight from the data behind the map.
Four maps at 616 acres behind 20.1 miles of shoreline — one island included. The 5.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 87% of the surface on the model — that's where the groceries are. End to end it runs roughly 2.3 mi, about 1.7 mi across. Lake County claims this one. If the bite dies, North Wilder is 2 mi to the south.
Start shallow in spring: lake whitefish sit in 8 to 25 ft that time of year. They don't go far with the seasons — 8 to 25 ft covers summer, 8 to 25 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 21 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
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 | 8 to 25 ft chart-limited; documented 15 to 45 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 25 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (21 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 25 ft chart-limited; documented 8 to 30 ft | dusk | Main-lake point (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 25 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (21 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 6 to 25 ft that time of year. They don't go far with the seasons — 8 to 25 ft covers summer, 8 to 25 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 21 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 25 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (21 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 25 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (21 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 8 to 25 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (21 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. Deep basin is the standout, a deep basin at roughly 21 ft, rated prime for winter walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |

| Winter | 8 to 25 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (21 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 8 to 25 ft, wintering in 8 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 8 to 25 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
