Rating depth structure for brook trout.

10-acre lake near Lake County. The lake tops out around 5 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
Tommy maps at 10 acres behind 0.7 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. The basin spans about 0.3 mi end to end. Lake County claims this one. Kitigan sits 2 mi west — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 1 to 5 ft. Through summer count on 2 to 5 ft; the winter hold is 1 to 5 ft. If you only fish one area, make it Deep basin: a deep basin around 4 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 5 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (4 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 5 ft chart-limited; documented 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 5 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (4 ft) | Small jigging spoon, Tungsten jig + plastic |
Tommy carries 3 mapped structure features, topping out (or rather bottoming out) at Main-lake point, about 5 ft down.
