Rating depth structure for brook trout.

56-acre lake near T2 R12 WELS. The lake tops out around 6 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 55 acres, worked by 1.7 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. It sits in Piscataquis County. Kelly Pond sits 1 mi southeast — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 1 to 6 ft. Even in summer they hold at 2 to 6 ft; winter keeps them in 1 to 6 ft. Put Deep basin first on the milk run — a deep basin near 6 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 | 1 to 6 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 6 ft | dawn & dusk | Deep basin (6 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 6 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 6 ft | dawn | Deep basin (6 ft) | Small jigging spoon, Tungsten jig + plastic |
