Rating depth structure for brook trout.

5-acre lake near TD R2 WELS. The lake tops out around 5 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Ketchum Lake maps at 5 acres behind 0.4 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Aroostook County claims this one. Presque Isle Lake sits 6 mi southwest — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 1 to 5 ft. Even in summer they hold at 2 to 5 ft; winter keeps them in 1 to 5 ft. The chart's best answer is Deep basin — deep basin, 5 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 5 ft | dawn & dusk | Deep basin (5 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 5 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 1 to 5 ft | dawn | Deep basin (5 ft) | Small jigging spoon, Tungsten jig + plastic |
3 pieces of structure are mapped here — Deep basin, around 5 ft, is the deepest of them.
