283-acre lake near Cook County. The lake tops out around 88 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here's the year, species by species, as the scoring engine sees it.
Frost maps at 285 acres behind 3.7 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. Roughly 36% 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. It sits in Cook County. Gordon sits 1 mi east — the closest neighbouring chart.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 26 to 88 ft, then a winter hold in 20 to 80 ft. Start at Deep basin. It's a deep basin holding about 75 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
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 | 10 to 40 ft | dawn & dusk | Main-lake point (22 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 26 to 88 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (75 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (22 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (75 ft) | White tube jig, Airplane jig |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Come spring, look for burbot tight to the bank in 25 to 70 ft. Expect a summer slide to 26 to 88 ft, then a winter hold in 15 to 60 ft. Start at Deep basin. It's a deep basin holding about 75 ft of water and rates prime come summer. Prime time lands in after dark and midday. A heavy jig + cut bait is the honest summer answer here.
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 | 25 to 70 ft | night & dusk | Deep basin (75 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 26 to 88 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (75 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (75 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (40 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
