3,607-acre lake in Rainy River District, Ontario. The lake tops out around 160 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here is how the season plays out for each species, straight from the data behind the map.
Crowrock Lake maps at 3,624 acres behind 59.9 miles of shoreline — 49 islands included. With a shoreline index of 7.1, this water is all arms and coves — edge habitat well beyond its acreage. 30% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 6.3 mi of water from one end to the other, 3.2 mi at the beam. Rainy River District claims this one. Caldwell Lake sits 2 mi south — the closest neighbouring chart.
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. The chart's best answer is Sharp break — drop-off, 39 ft, prime for winter. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Sharp break (39 ft) | Casting spoon over shoals, Jerkbait (shallow) |

A blade bait vertical or a small jigging spoon covers the summer program.
