67-acre lake in Vilas County, Wisconsin. The lake tops out around 38 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. What the data behind the map says about each species, season by season:
Jerms Lake maps at 67 acres behind 1.2 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 49% of the surface on the model — that's where the groceries are. Call it 0.4 mi long by 0.3 mi wide at the broadest reach. Vilas County claims this one. If the bite dies, Whitefish Lake is 1 mi to the east.
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 11 to 38 ft. Shoreline break is the standout, a drop-off at roughly 17 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Shoreline break (17 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Shoreline break (17 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 38 ft | dusk & night | Shoreline break (17 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 38 ft | dusk & dawn | Deep basin (32 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shoreline break (17 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (32 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (32 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 11 to 38 ft. If you only fish one area, make it Shoreline break: a drop-off around 17 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (17 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Shoreline break (17 ft) | Jerkbait, Blade bait |
| Winter | 11 to 38 ft | midday | Shoreline break (17 ft) | Blade bait, Hair jig |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Start at Shallow bay flat. It's a weed flat holding about 5 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (17 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Shoreline break (17 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 10 to 25 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Deep basin: a deep basin around 32 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shoreline break (17 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shoreline break (17 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Deep basin (32 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 10 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 5 ft that scores prime in spring. Best bite is early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (5 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (5 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Shoreline break (17 ft) | Tungsten ice jig + plastic, Tiny spoon |

Jerms Lake is about 38 ft (12 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target walleye, yellow perch, smallmouth bass, largemouth bass, crappie, bluegill, pumpkinseed on Jerms 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.
Shoreline break is the top-rated area: a drop-off in about 17 ft of water that rates prime for walleye in fall. The map above holds the full rated-spot list for every species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
