25-acre lake in Washburn County, Wisconsin. The lake tops out around 10 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 25 acres, worked by 1.2 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. Washburn County claims this one. Its nearest charted neighbour, Spring Lake, is 1 mi to the north.
Spring puts yellow perch in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 3 to 10 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 and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 10 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 10 ft | midday | Break off the point (5 ft) | Blade bait, Jigging spoon |
Spring crappie on Snag Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 3 to 10 ft, and by winter most fish are in 3 to 10 ft. The chart's best answer is Deep basin — deep basin, 9 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).
| 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 | 3 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 10 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 10 ft | midday | Deep basin (9 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring bluegill on Snag Lake hold shallow, usually 1 to 6 ft. They move out to 3 to 10 ft in summer and finish the year down in 3 to 10 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.
| 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 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 10 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 10 ft | midday | Deep basin (9 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 3 to 10 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 3 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 10 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
