1,023-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 8 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Coal Mine Lake maps at 1,023 acres behind 6.5 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 3 mi of water from one end to the other, 0.8 mi at the beam. Sheridan County claims this one. Its nearest charted neighbour, Hinsz Lake, is 9 mi to the northwest.
The spring pattern is a shallow one: yellow perch in 2 to 8 ft. The depth story barely changes: 2 to 8 ft through summer, 2 to 8 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 2 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.
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 | 2 to 8 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 8 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 8 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 8 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (8 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. There's no big seasonal slide here — summer means 2 to 8 ft, winter 2 to 8 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.
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 | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 8 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 8 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 8 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 8 ft.
