1,424-acre lake in Thunder Bay District, Ontario. The lake tops out around 290 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 1,437 acres wrapped in 24 miles of bank, broken up by 4 islands. With a shoreline index of 4.5, this water is all arms and coves — edge habitat well beyond its acreage. 56% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 5.2 mi of water from one end to the other, 1.7 mi at the beam. It sits in Thunder Bay District. If the bite dies, McLaurin Lake is 3 mi to the west.
