10-acre lake in Douglas County, Wisconsin. The lake tops out around 29 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Coffee Lake runs 10 acres with 0.5 miles of edge. Nearly circular (index 1.2), so the story is the bottom, not the bank. About 62% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. You'll find it in Douglas County. The nearest mapped water is Gander Lake, 0 mi to the southwest.
Spring yellow perch on Coffee Lake hold shallow, usually 3 to 12 ft. They move out to 9 to 29 ft in summer and finish the year down in 9 to 29 ft. Put Back-bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 9 to 29 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 29 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 29 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 9 to 29 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Back-bay flat (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Back-bay flat (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 9 to 29 ft | midday | Deep basin (26 ft) | Blade bait, Jigging spoon |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 10 to 25 ft; cold water stacks them in 9 to 29 ft. Deep basin is the standout, a deep basin at roughly 26 ft, rated prime for winter crappie. Plan around early morning and the evening in the warm months. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Deep basin (26 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Back-bay flat (6 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 9 to 29 ft | midday | Deep basin (26 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
The spring pattern is a shallow one: bluegill in 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for bluegill in spring. Plan around early morning and the evening in the warm months. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Back-bay flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Back-bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (26 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. The feeding windows run the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (2 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |

Coffee Lake is about 29 ft (9 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target yellow perch, largemouth bass, crappie, bluegill, pumpkinseed on Coffee 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.
Back-bay flat is the top-rated area: a weed flat in about 6 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.
