10-acre reservoir in Juneau County, Wisconsin. The lake tops out around 10 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, Trout Lake runs 10 acres with 1.1 miles of edge. The 2.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.5 mi of water from one end to the other. You'll find it in Juneau County. The nearest mapped water is Lake of the Dells, 6 mi to the southeast.
In spring, rainbow trout run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 2 to 10 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for spring rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 3 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 10 ft | dawn | Deep basin (9 ft) | Jigging spoon, Tube jig (white) |
The chart marks 3 structure features on Trout Lake; the deepest is Deep basin at about 9 ft.
