26-acre lake in Oneida County, Wisconsin. The lake tops out around 23 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. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Gross Lake runs 26 acres with 1.1 miles of edge. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 68% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.5 mi of water from one end to the other. The water lies in Oneida County. For a second option, Lassig Lake lies 1 mi southeast.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 7 to 23 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| 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 (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
