24-acre lake near Aitkin County. The lake tops out around 32 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
Sweetman maps at 24 acres behind 0.7 miles of shoreline. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. Roughly 45% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.3 mi end to end and 0.2 mi across at its widest. Aitkin County claims this one. Its nearest charted neighbour, Monson, is 1 mi to the southwest.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 32 ft. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (27 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 32 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (27 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 32 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (27 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 10 to 32 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (14 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 10 to 32 ft chart-limited; documented 15 to 35 ft | midday | Shoreline break (14 ft) | Blade bait, Jigging spoon |
Come spring, look for crappie tight to the bank in 2 to 8 ft. Expect a summer slide to 10 to 25 ft, then a winter hold in 10 to 32 ft. Start at Deep basin. It's a deep basin holding about 27 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.

When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 10 to 25 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |

| Winter | 10 to 25 ft | midday | Deep basin (27 ft) | Tungsten ice jig + plastic, Tiny spoon |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for pumpkinseed in spring. Plan around the evening and early morning in the warm months. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (4 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro tube, Sponge spider (fly) |

| Winter | 6 to 18 ft | dawn | Shallow bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts bowfin in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 14 ft; cold water stacks them in 8 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring bowfin. Plan around after dark and the evening in the warm months. A weedless frog or a swim jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dusk | Shallow bay flat (4 ft) | Weedless jig, Compact spinnerbait |
| Summer | 2 to 14 ft | night & dusk | Shallow bay flat (4 ft) | Weedless frog, Swim jig |
| Fall | 5 to 20 ft | dusk | Shallow bay flat (4 ft) | Swim jig, Compact spinnerbait |
| Winter | 8 to 25 ft | midday | Deep basin (27 ft) | Slow jig, Small blade bait |
