31-acre lake in Burnett County, Wisconsin. The lake tops out around 7 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
Johnson Lake maps at 31 acres behind 1.3 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.5 mi end to end and 0.2 mi across at its widest. It sits in Burnett County. Its nearest charted neighbour, Myrick Lake, is 0 mi to the northeast.
In spring, yellow perch run shallow here, mostly 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring largemouth bass on Johnson Lake hold shallow, usually 1 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold. 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 texas-rigged 10" worm or a deep-diving crankbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 7 ft | midday & dawn | Main-lake point (7 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 7 ft | midday | Break off the point (3 ft) | Blade bait, Jigging spoon |
Early season crappie use the shallows, holding in 2 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 2 to 7 ft. The chart's best answer is Deep basin — deep basin, 6 ft, prime for winter. Best bite is early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 7 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 7 ft | midday | Deep basin (6 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season bluegill use the shallows, holding in 1 to 6 ft. Expect a summer slide to 2 to 7 ft, then a winter hold in 2 to 7 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 small sponge spider (fly) or a micro tube jig and you're in the game.
| 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 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 7 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 7 ft | midday | Deep basin (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, pumpkinseed run shallow here, mostly 1 to 7 ft. Summer keeps them at 1 to 7 ft, and they winter in 2 to 7 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring pumpkinseed. Time it for the evening and early morning. You won't need more than a micro tube or a sponge spider (fly) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 1 to 7 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 2 to 7 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 7 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |

Anglers target yellow perch, largemouth bass, crappie, bluegill, pumpkinseed on Johnson Lake. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
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.
