142-acre lake near Frenchtown Twp. The lake tops out around 40 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Big Lyford Pond maps at 141 acres behind 2.9 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 67% of this chart. Call it 0.9 mi long by 0.4 mi wide at the broadest reach. Piscataquis County claims this one. If the bite dies, First West Branch Pond is 2 mi to the east.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in summer. Best bite is 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 | 2 to 15 ft | dawn & dusk | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (14 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (14 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 37 ft.
