897-acre lake near Cook County. The lake tops out around 65 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 905 acres of water rimmed by 20 miles of bank, with 6 islands in the mix. With a shoreline index of 4.7, this water is all arms and coves — edge habitat well beyond its acreage. 63% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 2.1 mi of water from one end to the other, 1.8 mi at the beam. The water lies in Cook County. Closest neighbour on DepthScout: Rog, 1 mi south of here.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 20 to 65 ft, and winter fish settle into 16 to 65 ft. The spot to know is Deep basin, a deep basin in about 55 ft of water that rates prime for lake trout in summer. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger 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 | 10 to 40 ft | dawn & dusk | Main-lake point (16 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 20 to 65 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (55 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (16 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 16 to 65 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (55 ft) | White tube jig, Airplane jig |
When the water first warms, lake whitefish slide up into 15 to 45 ft. By summer they slide out to 20 to 65 ft, and by winter most fish are in 20 to 65 ft. If you only fish one area, make it Deep basin: a deep basin around 55 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (29 ft) | Small jig + waxworm, Blade bait (small) |

When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. By summer they slide out to 20 to 65 ft, and by winter most fish are in 20 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 55 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (29 ft) | Small silver spoon, Tiny swim jig (white) |

Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. The chart's best answer is Break off the point — drop-off, 29 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (16 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (29 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (29 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (29 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Alpine hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (29 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| 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 |
