13-acre lake near Caswell. The lake tops out around 4 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 13 acres of water rimmed by 0.7 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.3 mi of water from one end to the other. The water lies in Aroostook County. Closest neighbour on DepthScout: Butterfield Lake, 2 mi south of here.
Spring puts brook trout in skinny water — 1 to 4 ft is the zone. Summer fish stay in 1 to 4 ft, and winter fish hold in 1 to 4 ft. Deep basin is the standout, a deep basin at roughly 4 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 1 to 4 ft | dawn & dusk | Deep basin (4 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 4 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 1 to 4 ft | dawn | Deep basin (4 ft) | Small jigging spoon, Tungsten jig + plastic |
