75-acre lake in Douglas County, Wisconsin. The lake tops out around 4 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. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 75 acres, worked by 1.5 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. It sits in Douglas County. If the bite dies, Alexander Lake is 1 mi to the northeast.
When the water first warms, northern pike slide up into 1 to 4 ft. There's no big seasonal slide here — summer means 1 to 4 ft, winter 1 to 4 ft. 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 | 1 to 4 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 1 to 4 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 1 to 4 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 1 to 4 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
