349-acre lake near Wright County. The lake tops out around 6 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Mary runs 349 acres with 3.6 miles of edge. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 1.4 mi with a 0.7-mi widest point. The water lies in Wright County. For a second option, Mink lies 2 mi west.
When the water first warms, walleye 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. Start at Break off the point. It's a drop-off holding about 6 ft of water and rates prime come fall. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

|---|---|---|---|---|
| Spring | 2 to 6 ft | dusk & dawn | Main-lake point (2 ft) | 1/8 oz jig + minnow, Hair jig |

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.

Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

Anglers target walleye, yellow perch, northern pike, largemouth bass, crappie, bluegill, pumpkinseed, brown bullhead, common carp on Mary. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species listed for the nearest surveyed lakes in the region, filtered to this lake's depth and habitat.
Break off the point is the top-rated area: a drop-off in about 6 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.
