15-acre lake in Vilas County, Wisconsin. The lake tops out around 12 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Little Mamie Lake draws 15 acres inside 0.6 miles of shoreline. A shoreline index of 1 says round and simple: fish relate to depth changes here, not shoreline features. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. You'll find it in Vilas County. The nearest mapped water is Little Pickerel Lake, 0 mi to the southwest.
Start shallow in spring: brook trout sit in 2 to 12 ft that time of year. They don't go far with the seasons — 4 to 12 ft covers summer, 2 to 12 ft covers winter. The spot to know is Deep basin, a deep basin in about 10 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 4 to 12 ft | dawn & dusk | Deep basin (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 12 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 2 to 12 ft | dawn | Deep basin (10 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 4 to 12 ft before dropping to 4 to 12 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 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 (3 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 12 ft | midday | Shoreline break (5 ft) | Blade bait, Jigging spoon |

Anglers target brook trout, largemouth bass on Little Mamie 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.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for largemouth bass in spring. Every other rated spot, per species and season, is on the map above.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
