Rating depth structure for largemouth bass.
Recent public catches load as you reach this section.
157-acre lake near Schoolcraft County. The lake tops out around 3 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
On the chart, Marblehead Lake draws 131 acres inside 2.4 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 0.9 mi long by 0.5 mi wide at the broadest reach. The water lies in Schoolcraft County. The nearest mapped water is Palmer Lake, 1 mi to the east.
Come spring, look for yellow perch tight to the bank in 1 to 3 ft. Through summer count on 1 to 3 ft; the winter hold is 1 to 3 ft. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
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 | 1 to 3 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 1 to 3 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (3 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 1 to 3 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (3 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 1 to 3 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (3 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: smallmouth bass sit in 1 to 3 ft that time of year. They don't go far with the seasons — 1 to 3 ft covers summer, 1 to 3 ft covers winter. The spot to know is Main-lake point, a point in about 2 ft of water that rates prime for smallmouth bass in fall. Warm-month bites cluster around early morning and the evening. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft chart-limited; documented 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 1 to 3 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (2 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 1 to 3 ft chart-limited; documented 8 to 25 ft | midday & dawn | Main-lake point (2 ft) | Jerkbait, Blade bait |
| Winter | 1 to 3 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (2 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: largemouth bass in 1 to 3 ft. The depth story barely changes: 1 to 3 ft through summer, 1 to 3 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft chart-limited; documented 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 1 to 3 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (2 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 1 to 3 ft chart-limited; documented 4 to 15 ft | midday & dawn | Main-lake point (2 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 1 to 3 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (2 ft) | Blade bait, Jigging spoon |
Start shallow in spring: crappie sit in 1 to 3 ft that time of year. They don't go far with the seasons — 1 to 3 ft covers summer, 1 to 3 ft covers winter. The spot to know is Deep basin, a deep basin in about 3 ft of water that rates good for crappie in winter. Warm-month bites cluster around early morning and the evening. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 1 to 3 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Shallow bay flat (2 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 1 to 3 ft chart-limited; documented 8 to 20 ft | dawn | Shallow bay flat (2 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 1 to 3 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (3 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 3 ft. Summer keeps them at 1 to 3 ft, and they winter in 1 to 3 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring bluegill. Time it for early morning and the evening. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.

Marblehead Lake is about 3 ft (1 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 yellow perch, smallmouth bass, largemouth bass, crappie, bluegill on Marblehead Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Shallow bay flat is the top-rated area: a weed flat in about 2 ft of water that rates prime for yellow perch in spring. The interactive chart above rates every spot for each 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.
