Rating depth structure for brook trout.

7-acre lake near Massachusetts Gore. 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. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 7 acres of water rimmed by 0.4 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. You'll find it in Franklin County. The nearest mapped water is Grants Pond, 1 mi to the east.
The spring pattern is a shallow one: brook trout in 1 to 4 ft. The depth story barely changes: 1 to 4 ft through summer, 1 to 4 ft in winter. Top water on the chart: Deep basin, a deep basin in the 4 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | dawn & dusk | Shallow bay flat (2 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 |
