Rating depth structure for rainbow trout.

11-acre lake in Lincoln County, Wisconsin. The lake tops out around 40 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Larson Lake runs 11 acres with 0.5 miles of edge. Nearly circular (index 1.1), so the story is the bottom, not the bank. About 21% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The water lies in Lincoln County. The nearest mapped water is Black Alder Lake, 1 mi to the south.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Shoreline break is the standout, a drop-off at roughly 18 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shoreline break (18 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shoreline break (18 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Shoreline break (18 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Shoreline break (18 ft) | Jigging spoon, Tube jig (white) |
Larson Lake carries 3 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 34 ft down.
