Rating depth structure for brook trout.

19-acre lake near Massachusetts Gore. 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. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 18 acres wrapped in 0.7 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. It sits in Franklin County. Its nearest charted neighbour, South Boundary Pond, is 1 mi to the west.
Spring brook trout on Grants Pond hold shallow, usually 1 to 6 ft. Depth-wise the year is flat: 2 to 6 ft in summer, 1 to 6 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 6 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | dawn & dusk | Shallow bay flat (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 | open water | Small spoon (orange), Spinner |
| Winter | 1 to 6 ft | dawn | Deep basin (6 ft) | Small jigging spoon, Tungsten jig + plastic |
