114-acre lake near Chippewa County. The lake tops out around 9 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 90 acres wrapped in 2.1 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 0.6 mi end to end and 0.5 mi across at its widest. It sits in Chippewa County. If the bite dies, Parish Lake is 4 mi to the northwest.
Start shallow in spring: walleye sit in 2 to 9 ft that time of year. They don't go far with the seasons — 3 to 9 ft covers summer, 3 to 9 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 5 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dusk & dawn | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 9 ft | dusk & dawn | Break off the point (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 9 ft | dusk & night | Break off the point (5 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 9 ft | dusk & dawn | Deep basin (9 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 2 to 9 ft is the zone. Summer fish stay in 3 to 9 ft, and winter fish hold in 3 to 9 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

Gravel Lake is about 9 ft (3 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target walleye, yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed on Gravel Lake. 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 5 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.
