Rating depth structure for brook trout.

42-acre lake near Rainbow Twp. The lake tops out around 48 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.
Traced from the shoreline, Big Beaver Pond runs 43 acres with 1.2 miles of edge. Nearly circular (index 1.4), so the story is the bottom, not the bank. About 54% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.5 mi end to end and 0.2 mi across at its widest. You'll find it in Piscataquis County. Closest neighbour on DepthScout: Little Minister Pond, 1 mi east of here.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Main-lake point, a point in the 7 ft range, prime in spring. 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 | 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 (7 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 (7 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 45 ft.
