53-acre lake in Sawyer County, Wisconsin. The lake tops out around 12 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Schoolhouse Lake runs 53 acres with 1.3 miles of edge. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. 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 0.4 mi long by 0.3 mi wide at the broadest reach. The water lies in Sawyer County. For a second option, Durphee Lake lies 0 mi south.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Even in summer they hold at 4 to 12 ft; winter keeps them in 4 to 12 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 12 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 12 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 12 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 4 to 12 ft, and winter fish settle into 4 to 12 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 12 ft | dawn & dusk | Break off the point (5 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 12 ft | midday & dawn | Break off the point (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 12 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Summer keeps them at 4 to 12 ft, and they winter in 4 to 12 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 4 to 12 ft | dawn & dusk | Break off the point (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 4 to 12 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 4 to 12 ft | midday | Break off the point (5 ft) | Blade bait, Hair jig |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 4 to 12 ft, wintering in 4 to 12 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Break off the point (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 12 ft | midday | Break off the point (5 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 4 to 12 ft, and winter fish settle into 4 to 12 ft. Deep basin is the standout, a deep basin at roughly 10 ft, rated prime for winter crappie. Time it for early morning and the evening. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 4 to 12 ft | dawn & dusk | Break off the point (5 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 4 to 12 ft | dawn | Break off the point (5 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 4 to 12 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for bluegill in spring. Warm-month bites cluster around early morning and the evening. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| 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 | 3 to 12 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 4 to 12 ft | midday | Break off the point (5 ft) | Micro jig + waxworm, Small spoon tipped |
