57-acre lake in Vilas County, Wisconsin. The lake tops out around 18 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What the data behind the map says about each species, season by season:
The outline encloses 57 acres, worked by 1.6 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. About 83% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. It sits in Vilas County. Its nearest charted neighbour, Finley Lake, is 0 mi to the east.
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Break off the point is the standout, a drop-off at roughly 8 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 18 ft | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 18 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 18 ft | dusk & dawn | Deep basin (15 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| 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 | 5 to 18 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 18 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 18 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, muskellunge slide up into 3 to 12 ft. By summer they slide out to 5 to 18 ft, and by winter most fish are in 5 to 18 ft. If you only fish one area, make it Break off the point: a drop-off around 8 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a double-10 bucktail or a topwater (walk-the-dog / creeper) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 5 to 18 ft | dusk & dawn | Main-lake point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 5 to 18 ft | midday & dusk | Break off the point (8 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 5 to 18 ft | midday | Deep basin (15 ft) | Large rubber, crawled slow |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. They move out to 5 to 18 ft in summer and finish the year down in 5 to 18 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 18 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 5 to 18 ft | midday | Break off the point (8 ft) | Blade bait, Hair jig |
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is a 5 to 18 ft game here, winter a 5 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 18 ft | midday | Break off the point (8 ft) | Blade bait, Jigging spoon |
Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 5 to 18 ft in summer and finish the year down in 5 to 18 ft. If you only fish one area, make it Deep basin: a deep basin around 15 ft that scores prime in winter. Best bite is early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.
| 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 | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 18 ft | dawn | Break off the point (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 18 ft | midday | Deep basin (15 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
