Rating depth structure for northern pike.

276-acre lake near Marlboro. The lake tops out around 9 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Black Mud Lake maps at 276 acres behind 2.6 miles of shoreline. Nearly circular (index 1.1), 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 0.8 mi end to end and 0.7 mi across at its widest. Division No. 14 claims this one. If the bite dies, Millers Lake is 2 mi to the east.
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 3 to 9 ft, and by winter most fish are in 3 to 9 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) |
| Summer | 3 to 9 ft | dawn & dusk | Break off the point (4 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 3 to 9 ft | midday & dawn | Break off the point (4 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 3 to 9 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: yellow perch in 2 to 9 ft. The depth story barely changes: 3 to 9 ft through summer, 3 to 9 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 9 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 9 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 9 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + spikes, Rattle spoon (small) |
