861-acre lake in Sudbury District, Ontario. The lake tops out around 180 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.
Traced from the shoreline, Walker Lake runs 864 acres with 13.7 miles of edge, with 23 islands in the mix. With a shoreline index of 3.3, this water is all arms and coves — edge habitat well beyond its acreage. 15% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 2.9 mi of water from one end to the other, 1.3 mi at the beam. You'll find it in Sudbury District. The nearest mapped water is Little Bear Lake, 1 mi to the south.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Top water on the chart: Secondary point, a point in the 19 ft range, prime in spring. 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.

Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
