160-acre lake near St. Louis County. The lake tops out around 5 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 depth data here comes from a DNR lake survey. Species by species, here's what the data says the year looks like.
Mud Hen maps at 160 acres behind 2.3 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than 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. End to end it runs roughly 0.7 mi, about 0.6 mi across. It sits in St. Louis County. If the bite dies, Coe is 1 mi to the northwest.
The spring pattern is a shallow one: yellow perch in 1 to 5 ft. The depth story barely changes: 2 to 5 ft through summer, 2 to 5 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. 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 | 1 to 5 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 5 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 1 to 5 ft. There's no big seasonal slide here — summer means 2 to 5 ft, winter 2 to 5 ft. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. The feeding windows run 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 | 1 to 5 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 5 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 5 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 5 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 5 ft. Through summer count on 1 to 5 ft; the winter hold is 2 to 5 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 small sponge spider (fly) or a micro tube jig is the honest summer answer here.

| Winter | 2 to 5 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for brown bullhead tight to the bank in 1 to 5 ft. Through summer count on 1 to 5 ft; the winter hold is 2 to 5 ft. Start at Deep basin. It's a deep basin holding about 5 ft of water and rates prime come winter. Prime time lands in after dark and the evening.

In spring, walleye run shallow here, mostly 1 to 5 ft. Summer keeps them at 2 to 5 ft, and they winter in 2 to 5 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 5 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
