22-acre lake in Algoma District, Ontario. The lake tops out around 40 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 1960, a decades-old survey (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
Crow Lake maps at 22 acres behind 0.9 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. About 48% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Algoma District. Its nearest charted neighbour, Bun Lake, is 1 mi to the west.
Spring brook trout on Crow Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Break off the point — drop-off, 28 ft, prime for summer. Prime time lands in 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 (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (28 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | open water | Small jigging spoon, Tungsten jig + plastic |
