20-acre lake near New Canada. The lake tops out around 21 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.
The outline encloses 19 acres, worked by 0.7 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 92% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Aroostook County. If the bite dies, First Sly Brook Lake is 1 mi to the northwest.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 6 to 21 ft, then a winter hold in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 19 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 21 ft | dawn & dusk | Deep basin (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (19 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 19 ft.
