106-acre lake in Algoma District, Ontario. The lake tops out around 65 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Gravelpit Lake maps at 107 acres behind 3 miles of shoreline. With a 2.1 development index there's bank structure worth casting at, in moderation. Roughly 73% of the water is 15 ft or less, the band where the food chain lives. Call it 0.9 mi long by 0.4 mi wide at the broadest reach. Algoma District claims this one. Its nearest charted neighbour, Link Lake, is 1 mi to the south.
Spring brook trout on Gravelpit 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 11 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 (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (11 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (11 ft) | Small jigging spoon, Tungsten jig + plastic |
