219-acre lake near St. Louis County. The lake tops out around 60 ft. The depth data here comes from the Minnesota DNR survey of 1969, a decades-old survey (the DNR's original lake-survey map). Species by species, here's what the data says the year looks like.
Spring maps at 219 acres behind 4.5 miles of shoreline. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. 19% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1.8 mi of water from one end to the other, 0.4 mi at the beam. It sits in St. Louis County. If the bite dies, Tooth is 2 mi to the north.
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Summer pushes them deeper, 18 to 60 ft, and winter fish settle into 18 to 60 ft. The spot to know is Deep basin, a deep basin in about 60 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (52 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 18 to 60 ft | dawn | Deep basin (60 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (19 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 18 to 60 ft | midday & dawn | Deep basin (60 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Summer pushes them deeper, 18 to 60 ft, and winter fish settle into 20 to 60 ft. The spot to know is Deep basin, a deep basin in about 60 ft of water that rates prime for cisco (lake herring) in summer. Warm-month bites cluster around early morning. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (60 ft) | Small silver spoon, Tiny swim jig (white) |

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. The spot to know is Shallow bay flat, a feeding flat in about 6 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. 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 (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

| Winter | 15 to 35 ft | midday & dawn | Deep basin (60 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a feeding flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |

Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 6 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (19 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
