59-acre lake in Thunder Bay District, Ontario. The lake tops out around 9 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Forrester Lake maps at 58 acres behind 1.7 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.6 mi with a 0.3-mi widest point. It sits in Thunder Bay District. Its nearest charted neighbour, Kenogamisis Lake, is 2 mi to the west.
In spring, yellow perch run shallow here, mostly 2 to 9 ft. Summer keeps them at 3 to 9 ft, and they winter in 3 to 9 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
