1,241-acre lake near Gogebic County. The lake tops out around 40 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. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 1,135 acres wrapped in 6.9 miles of bank. With a 1.5 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 68% of the surface — that's where the groceries are. The basin spans about 2.2 mi end to end and 1.4 mi across at its widest. Gogebic County claims this one. Long Lake sits 2 mi east — the closest neighbouring chart.
When the water first warms, lake trout slide up into 10 to 40 ft. There's no big seasonal slide here — summer means 12 to 40 ft, winter 10 to 40 ft. Start at Deep basin. It's a deep basin holding about 40 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (7 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 12 to 40 ft | dawn | Deep basin (40 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 8 to 40 ft | dusk & dawn | Break off the point (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 10 to 40 ft | dawn | Deep basin (40 ft) | White tube jig, Airplane jig |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Deep basin is the standout, a deep basin at roughly 40 ft, rated prime for winter walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (7 ft) | 1/8 oz jig + minnow, Hair jig |

| Winter | 20 to 40 ft | dusk & dawn | Deep basin (40 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Deep basin, a deep basin in the 40 ft range, prime in fall. Time it for early morning. 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Winter | 15 to 35 ft | midday & dawn | Deep basin (40 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for muskellunge tight to the bank in 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 7 ft that scores prime in fall. Best bite is the evening and early morning. A double-10 bucktail or a topwater (walk-the-dog / creeper) is the honest summer answer here.
| 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 (7 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |

If you only fish one area, make it Break off the point: a drop-off around 7 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |

It's a weed flat holding about 1 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
