36-acre lake near St. Louis County. The lake tops out around 6 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Foss runs 36 acres with 1 miles of edge. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. You'll find it in St. Louis County. Closest neighbour on DepthScout: Tamarack, 1 mi west of here.
Come spring, look for yellow perch tight to the bank in 2 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 2 to 6 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is 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 | 2 to 6 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 6 ft that time of year. They don't go far with the seasons — 2 to 6 ft covers summer, 2 to 6 ft covers winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 6 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 6 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 6 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 2 to 6 ft. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 6 ft chart-limited; documented 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 6 ft chart-limited; documented 6 to 18 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 6 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season pumpkinseed use the shallows, holding in 1 to 6 ft. Even in summer they hold at 1 to 6 ft; winter keeps them in 2 to 6 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.

Foss is about 6 ft (2 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, northern pike, bluegill, pumpkinseed on Foss.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Scroll up to the map for the complete spot list by 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.
Fishing on Foss is regulated by the Minnesota DNR. Check the official Minnesota regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
