389-acre lake in Kenora District, Ontario. The lake tops out around 79 ft. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 390 acres wrapped in 8.3 miles of bank, with 3 islands in the mix. A development index of 3 means a maze of bays and points: far more casting targets than a round bowl of the same size. 52% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1.4 mi of water from one end to the other, 1.2 mi at the beam. Kenora District claims this one. If the bite dies, South Crook Lake is 1 mi to the south.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 24 to 79 ft in summer and finish the year down in 20 to 79 ft. If you only fish one area, make it Deep basin: a deep basin around 78 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (21 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 79 ft | dawn | Deep basin (78 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 79 ft | dawn | Deep basin (78 ft) | White tube jig, Airplane jig |
Crook Lake carries 7 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 78 ft down.
