10-acre lake in Bayfield County, Wisconsin. The lake tops out around 14 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 10 acres, worked by 0.7 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Figure 0.3 mi of water from one end to the other. Bayfield County claims this one. Porter Lakes sits 1 mi northwest — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 4 to 14 ft, wintering in 4 to 14 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 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 14 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Jo Ann Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 4 to 14 ft, and by winter most fish are in 4 to 14 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| 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 14 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 14 ft | midday & dawn | Shoreline break (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 14 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 4 to 14 ft, then a winter hold in 4 to 14 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 | 4 to 14 ft | dawn & dusk | Shoreline break (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 14 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 14 ft | midday | Shoreline break (6 ft) | Blade bait, Jigging spoon |
Spring crappie on Jo Ann Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 4 to 14 ft, and by winter most fish are in 4 to 14 ft. The chart's best answer is Deep basin — deep basin, 12 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 | 4 to 14 ft | dawn & dusk | Shoreline break (6 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 4 to 14 ft | dawn | Shoreline break (6 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 4 to 14 ft | midday | Deep basin (12 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring bluegill on Jo Ann Lake hold shallow, usually 1 to 6 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 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 | 4 to 14 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 4 to 14 ft | midday | Shoreline break (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 14 ft | midday | Deep basin (12 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 4 to 14 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 |

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. Open the map above to see every rated spot for each 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.
