10-acre lake in Iron County, Wisconsin. The lake tops out around 17 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. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 10 acres, worked by 0.5 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. 54% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. It sits in Iron County. Sandy Beach Lake sits 1 mi east — the closest neighbouring chart.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is a 5 to 17 ft game here, winter a 5 to 17 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| 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 17 ft | dawn & dusk | Shoreline break (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 17 ft | midday | Shoreline break (8 ft) | Blade bait, Jigging spoon |

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. Open the map above to see every rated spot for each species and season.
For largemouth bass, 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.
