218-acre lake near Massachusetts Gore. The lake tops out around 11 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.
Massachusetts Bog maps at 218 acres behind 5.8 miles of shoreline. With a shoreline index of 2.8, this water is all arms and coves — edge habitat well beyond its acreage. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 2 mi with a 0.4-mi widest point. It sits in Franklin County. If the bite dies, South Boundary Pond is 4 mi to the south.
Spring brook trout on Massachusetts Bog hold shallow, usually 1 to 11 ft. Depth-wise the year is flat: 3 to 11 ft in summer, 2 to 11 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 8 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 11 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 11 ft | dawn & dusk | Deep basin (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 11 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 11 ft | dawn | Deep basin (8 ft) | Small jigging spoon, Tungsten jig + plastic |
