155-acre lake in Iron County, Wisconsin. The lake tops out around 21 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The season-by-season read for each species follows, from the map's own numbers.
Wilson Lake maps at 155 acres behind 2.8 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 82% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.9 mi with a 0.5-mi widest point. It sits in Iron County. Brandt Lake sits 1 mi northeast — the closest neighbouring chart.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 6 to 21 ft before dropping to 6 to 21 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. 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 (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 21 ft | dawn | Deep basin (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 21 ft | midday | Deep basin (18 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 21 ft | midday & dawn | Deep basin (18 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 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 bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 | 8 to 20 ft | dawn & dusk | Break off the point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for muskellunge tight to the bank in 3 to 12 ft. Expect a summer slide to 6 to 21 ft, then a winter hold in 6 to 21 ft. Start at Break off the point. It's a drop-off holding about 9 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A double-10 bucktail or a topwater (walk-the-dog / creeper) is the honest summer answer here.
| 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 | 6 to 21 ft | dusk & dawn | Main-lake point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 6 to 21 ft | midday & dusk | Break off the point (9 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 6 to 21 ft | midday | Deep basin (18 ft) | Large rubber, crawled slow |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 6 to 21 ft game here, winter a 6 to 21 ft one. Start at Main-lake point. It's a point holding about 8 ft of water and rates prime come fall. The feeding windows run 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 | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 6 to 21 ft | dawn & dusk | Break off the point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 21 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 6 to 21 ft | midday | Break off the point (9 ft) | Blade bait, Hair jig |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 6 to 21 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is 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 (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (9 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 | 6 to 21 ft | midday | Break off the point (9 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 6 to 21 ft game here, winter a 6 to 21 ft one. Start at Deep basin. It's a deep basin holding about 18 ft of water and rates prime come winter. The feeding windows run 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 (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
