Rating depth structure for brook trout.

625-acre lake near T6 R8 WELS. The lake tops out around 34 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.
Drawn out, this is 624 acres of water rimmed by 7.2 miles of bank — 2 islands included. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. About 52% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 2.4 mi long by 1 mi wide at the broadest reach. You'll find it in Penobscot County. For a second option, Hay Pond lies 2 mi northwest.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Spring brook trout concentrate at Creek inflow, a prime-rated inflow / creek mouth around 4 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Creek inflow (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Creek inflow (4 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Creek inflow (4 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, landlocked salmon run shallow here, mostly 1 to 15 ft. Summer pushes them deeper, 10 to 34 ft, and winter fish settle into 9 to 34 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 4 ft, rated prime for spring landlocked salmon. Time it for early morning and the evening. You won't need more than a dodger + streamer down deep or a thin spoon on lead core most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Creek inflow (4 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 10 to 34 ft | dawn & dusk | Deep basin (32 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Creek inflow (4 ft) | Casting spoon at the mouths, Streamers |
| Winter | 9 to 34 ft | dawn | Deep basin (32 ft) | Small jigging spoon, Swedish pimple + smelt |
