24-acre lake in Iron County, Wisconsin. The lake tops out around 6 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. What the data behind the map says about each species, season by season:
Traced from the shoreline, Mud Lake runs 24 acres with 0.8 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 0.3 mi end to end and 0.2 mi across at its widest. The water lies in Iron County. The nearest mapped water is Horseshoe Lake, 1 mi to the northwest.
When the water first warms, yellow perch slide up into 2 to 6 ft. There's no big seasonal slide here — summer means 2 to 6 ft, winter 2 to 6 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in 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 | 2 to 6 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 6 ft. The depth story barely changes: 2 to 6 ft through summer, 2 to 6 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. 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 6 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 6 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 6 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 6 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: crappie in 2 to 6 ft. The depth story barely changes: 2 to 6 ft through summer, 2 to 6 ft in winter. Top water on the chart: Deep basin, a deep basin in the 5 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 6 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 6 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 6 ft | midday | Deep basin (5 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring puts bluegill in skinny water — 1 to 6 ft is the zone. Summer fish stay in 2 to 6 ft, and winter fish hold in 2 to 6 ft. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A small sponge spider (fly) or a micro tube jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 6 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 6 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 6 ft | midday | Deep basin (5 ft) | Tungsten ice jig + plastic, Tiny spoon |

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 1 to 6 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 2 to 6 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 6 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |

Mud Lake is about 6 ft (2 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, northern pike, crappie, bluegill, pumpkinseed on Mud Lake. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Scroll up to the map for the complete spot list by species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
