274-acre lake near T15 R9 WELS. The lake tops out around 88 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 273 acres, worked by 3.9 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 8% of this chart. Tip to tip the water measures near 1.7 mi with a 0.5-mi widest point. Aroostook County claims this one. Little Black Pd North sits 1 mi north — the closest neighbouring chart.
Spring brook trout on Deboullie Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 25 ft that grades prime for summer. The feeding windows run 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 | 2 to 15 ft | dawn & dusk | Main-lake point (17 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (17 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 20 to 60 ft before dropping to 10 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 25 ft of water that rates prime for arctic char in summer. Plan around early morning in the warm months. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
