6,051-acre lake in Kenora District, Ontario. The lake tops out around 90 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 27 to 90 ft; cold water stacks them in 20 to 80 ft. Top water on the chart: Deep basin, a deep basin in the 90 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.

Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Sharp break first on the milk run — a drop-off near 28 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
