Rating depth structure for brook trout.

37-acre lake near Saint Francis. The lake tops out around 10 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
On the chart, McLean Lake draws 36 acres inside 1.4 miles of shoreline. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 0.6 mi, about 0.2 mi across. You'll find it in Aroostook County. Closest neighbour on DepthScout: Third Wallagrass Lake, 2 mi east of here.
The spring pattern is a shallow one: brook trout in 1 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 2 to 10 ft in winter. Top water on the chart: Deep basin, a deep basin in the 10 ft range, prime in summer. 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 | 1 to 10 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 10 ft | dawn & dusk | Deep basin (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 10 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 10 ft | dawn | Deep basin (10 ft) | Small jigging spoon, Tungsten jig + plastic |
