586-acre lake in Sudbury District, Ontario. The lake tops out around 62 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Squirrel Lake draws 587 acres inside 9.7 miles of shoreline. An index of 2.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 26% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 2 mi with a 1.3-mi widest point. You'll find it in Sudbury District. The nearest mapped water is Little Pogamasing Lake, 2 mi to the east.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 19 to 62 ft; cold water stacks them in 16 to 62 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.
