566-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 14 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
Drawn out, this is 566 acres of water rimmed by 3.8 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 1.6 mi end to end and 0.7 mi across at its widest. You'll find it in Ramsey County. The nearest mapped water is Devils Lake, 14 mi to the south.
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 4 to 14 ft game here, winter a 4 to 14 ft one. Start at Deep basin. It's a deep basin holding about 14 ft of water and rates prime come fall. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 14 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 4 to 14 ft before dropping to 4 to 14 ft for winter. The spot to know is Break off the point, a drop-off in about 8 ft of water that rates prime for northern pike in fall. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 14 ft | dawn & dusk | Break off the point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 14 ft | midday & dawn | Break off the point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 14 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
