184-acre lake near Baraga County. The lake tops out around 34 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 141 acres wrapped in 2.9 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 87% of this chart. Call it 0.9 mi long by 0.4 mi wide at the broadest reach. Baraga County claims this one. part of Plumbago Creek Lake sits 5 mi northeast — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 10 to 34 ft, wintering in 10 to 34 ft. Top water on the chart: Break off the point, a drop-off in the 10 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
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 | Break off the point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 10 to 34 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 34 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 34 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (33 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 34 ft. Deep basin is the standout, a deep basin at roughly 33 ft, rated prime for fall yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Early season muskellunge use the shallows, holding in 3 to 12 ft. Summer is an 8 to 25 ft game here, winter a 10 to 34 ft one. The chart's best answer is Break off the point — drop-off, 10 ft, prime for fall. Best bite is the evening and early morning. Tie on a double-10 bucktail or a topwater (walk-the-dog / creeper) and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (1 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Break off the point (10 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |

Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 10 to 34 ft. Put Break off the point first on the milk run — a drop-off near 10 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.

Anglers target walleye, yellow perch, muskellunge, smallmouth bass, largemouth bass, crappie, bluegill on Big 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.
Break off the point is the top-rated area: a drop-off in about 10 ft of water that rates prime for walleye in fall. The map above holds the full rated-spot list for every 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.
