1,217-acre lake near Marshall County. The lake tops out around 20 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 1,186 acres, worked by 7.4 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 83% of the surface on the model — that's where the groceries are. Figure 1.7 mi of water from one end to the other, 1.7 mi at the beam. Marshall County claims this one. Its nearest charted neighbour, Red Iron South Lake, is 2 mi to the east.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 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.
| 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 | 6 to 20 ft | dawn | Deep basin (17 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (17 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (17 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 6 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 17 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) 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) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 6 to 20 ft | dawn & dusk | Break off the point (9 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 6 to 20 ft | midday | Deep basin (17 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 6 to 20 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 20 ft | midday | Deep basin (17 ft) | Tungsten ice jig + plastic, Tiny spoon |
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) |

In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. Break off the point is the standout, a drop-off at roughly 9 ft, rated prime for fall 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 |
| Summer | 6 to 20 ft | dusk & dawn | Break off the point (9 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
