110-acre lake near TA R11 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. Every species below gets its seasonal read from the same numbers driving the chart.
Big Rocky Pond maps at 109 acres behind 2.8 miles of shoreline — one island included. A middling shoreline index (1.9) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.9 mi end to end and 0.4 mi across at its widest. It sits in Piscataquis County. If the bite dies, Birch Ridge Pond #1 is 1 mi to the southwest.
Come spring, look for brook trout tight to the bank in 1 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 1 to 6 ft. Start at Deep basin. It's a deep basin holding about 6 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| 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 |
