98-acre lake in Marathon County, Wisconsin. The lake tops out around 16 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Mayflower Lake runs 98 acres with 2.7 miles of edge. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 98% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 1.2 mi with a 0.2-mi widest point. The water lies in Marathon County. For a second option, Mud Lake lies 2 mi west.
Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 5 to 16 ft game here, winter a 5 to 16 ft one. The chart's best answer is Break off the point — drop-off, 7 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
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 | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 16 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (7 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 16 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (7 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 16 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (14 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 5 to 16 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 5 to 16 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (7 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 5 to 16 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (7 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 5 to 16 ft, and winter fish settle into 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

6 pieces of structure are mapped here — Deep basin, around 14 ft, is the deepest of them.

Mayflower Lake is about 16 ft (5 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 walleye, northern pike, largemouth bass on Mayflower 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.
Break off the point is the top-rated area: a drop-off in about 7 ft of water that rates prime for walleye in fall. Every other rated spot, per species and season, is on the map above.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Yes — per Wisconsin DNR fish-stocking summary records, Mayflower Lake was most recently stocked 2025 with 500 walleye (large fingerling). The full stocking history is listed above.
