354-acre lake in Kenora District, Ontario. The lake tops out around 53 ft. The depth data here comes from the Ontario MNRF survey of 1990 (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Jackfish Lake draws 356 acres inside 4.7 miles of shoreline, with a single island in the mix. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. 24% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 1.4 mi with a 0.8-mi widest point. You'll find it in Kenora District. The nearest mapped water is White Otter Lake, 1 mi to the west.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 16 to 53 ft; cold water stacks them in 13 to 53 ft. Top water on the chart: Deep basin, a deep basin in the 53 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.

A bucktail or a weedless spoon over cabbage covers the summer program.
