31-acre lake near Otter Tail County. The lake tops out around 12 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Unnamed Lake (Otter Tail County) maps at 31 acres behind 2.2 miles of shoreline. That shoreline is heavily fingered (development index 2.8) — bays, points and pockets everywhere, which multiplies the fishable edge. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Tip to tip the water measures near 0.7 mi with a 0.2-mi widest point. Otter Tail County claims this one. Prairie sits 2 mi north — the closest neighbouring chart.
In spring, walleye run shallow here, mostly 3 to 12 ft. Summer keeps them at 4 to 12 ft, and they winter in 4 to 12 ft. Deep basin is the standout, a deep basin at roughly 12 ft, rated prime for winter 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 | 3 to 12 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Break off the point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 4 to 12 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (3 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. The depth story barely changes: 4 to 12 ft through summer, 4 to 12 ft in winter. Top water on the chart: Back-bay flat, a weed flat in the 6 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 | Back-bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |

When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 4 to 12 ft, and by winter most fish are in 4 to 12 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 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 (2 ft) | #5 inline spinner, Spoon (red/white) |

When the water first warms, smallmouth bass slide up into 3 to 12 ft. There's no big seasonal slide here — summer means 4 to 12 ft, winter 4 to 12 ft. If you only fish one area, make it Break off the point: a drop-off around 3 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 4 to 12 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (3 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 4 to 12 ft chart-limited; documented 8 to 25 ft | midday & dawn | Break off the point (3 ft) | Jerkbait, Blade bait |
| Winter | 4 to 12 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (3 ft) | Blade bait, Hair jig |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 4 to 12 ft, then a winter hold in 4 to 12 ft. Start at Shallow bay flat. It's a weed flat holding about 2 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.

Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Warm water sends them out to 3 to 12 ft; cold water stacks them in 4 to 12 ft. Top water on the chart: Deep basin, a deep basin in the 12 ft range, prime in winter. Fish it in the evening and you'll meet the bite. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.
