Rating depth structure for largemouth bass.
Shared by DepthScout anglers. Exact spots stay private, always.
90-acre lake in Oneida County, Wisconsin. The lake tops out around 7 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 90 acres, worked by 1.5 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.5 mi with a 0.4-mi widest point. Oneida County claims this one. Tim Lynn Lake sits 1 mi southwest — the closest neighbouring chart.
In spring, walleye run shallow here, mostly 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Shoreline break is the standout, a drop-off at roughly 3 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 | 2 to 7 ft | dusk & dawn | Shoreline break (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 7 ft | dusk & dawn | Shoreline break (3 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 7 ft | dusk & night | Shoreline break (3 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 7 ft | dusk & dawn | Deep basin (6 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 2 to 7 ft. The depth story barely changes: 2 to 7 ft through summer, 2 to 7 ft in winter. 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 | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for largemouth bass tight to the bank in 1 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. Start at Shallow bay flat. 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 |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 7 ft | midday | Shoreline break (3 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 2 to 7 ft. If you only fish one area, make it Deep basin: a deep basin around 6 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 7 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 7 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 7 ft | midday | Deep basin (6 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 2 to 7 ft in summer and finish the year down in 2 to 7 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 | 2 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 7 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 7 ft | midday | Deep basin (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: pumpkinseed sit in 1 to 7 ft that time of year. They don't go far with the seasons — 1 to 7 ft covers summer, 2 to 7 ft covers winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in the evening and early morning and you'll meet the bite. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 1 to 7 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 2 to 7 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 7 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |

Oatmeal Lake is about 7 ft (2 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target walleye, yellow perch, largemouth bass, crappie, bluegill, pumpkinseed on Oatmeal Lake. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Shoreline break is the top-rated area: a drop-off in about 3 ft of water that rates prime for walleye in fall. Every other rated spot, per species and season, is on the map above.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Oatmeal Lake is regulated by the Wisconsin DNR. Check the official Wisconsin regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
