325-acre lake in Kenosha County, Wisconsin. The lake tops out around 33 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Lake Mary maps at 325 acres behind 4.4 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. Roughly 68% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 1.1 mi long by 0.8 mi wide at the broadest reach. It sits in Kenosha County. Its nearest charted neighbour, Elizabeth Lake, is 1 mi to the southwest.
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 10 to 33 ft before dropping to 10 to 33 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 15 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.
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 | 10 to 33 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (15 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 33 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (15 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 33 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (28 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 10 to 33 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 4 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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 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 | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 10 to 33 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |

| Winter | 10 to 33 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 10 to 25 ft game here, winter a 10 to 33 ft one. Start at Deep basin. It's a deep basin holding about 28 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.

Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Start at Shallow bay flat. It's a weed flat holding about 4 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |

Lake Mary is about 33 ft (10 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, yellow perch, northern pike, largemouth bass, crappie, bluegill, smallmouth bass on Lake Mary. 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 15 ft of water that rates prime for walleye in fall. Open the map above to see every rated spot for each species and season.
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, Lake Mary was most recently stocked 2025 with 211 smallmouth bass (large fingerling). The full stocking history is listed above.
