147-acre lake near Lake County. The lake tops out around 26 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 149 acres, worked by 6 miles of shoreline, broken up by an island. A development index of 3.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 78% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 1 mi, about 0.8 mi across. Lake County claims this one. If the bite dies, Bruin is 1 mi to the west.
In spring, cisco (lake herring) run shallow here, mostly 7 to 26 ft. Summer keeps them at 8 to 26 ft, and they winter in 8 to 26 ft. Spring cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 22 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
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 | 7 to 26 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (22 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 26 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (22 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (12 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 8 to 26 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (22 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 8 to 26 ft, wintering in 8 to 26 ft. Top water on the chart: Break off the point, a drop-off in the 12 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

| 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 |
| Summer | 8 to 26 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (12 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

| Winter | 8 to 26 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (22 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 26 ft, and winter fish settle into 8 to 26 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

| 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 |

| Winter | 8 to 26 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (22 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| 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 | Break off the point (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (12 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 |
In spring, rock bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 5 to 20 ft before dropping to 8 to 26 ft for winter. Summer rock bass concentrate at Main-lake point, a prime-rated point around 8 ft. Fish it in the evening and you'll meet the bite. You won't need more than a ned rig (small) or a marabou jig most summer days.

Early season crappie use the shallows, holding in 2 to 8 ft. Expect a summer slide to 10 to 25 ft, then a winter hold in 8 to 26 ft. Put Deep basin first on the milk run — a deep basin near 22 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
