French River is the overflow from Lake Nipissing into Georgian Bay. It is about 40 miles long, and has a total fall of about 65 feet. It combines the waters of three other rivers—Wanapitei, Murdock, and Pick‐erel—in one great east-west watercourse, known in different portions as Ox Bay, Wanapitei Bay, and French River. The combined waters turn abruptly south and southeastward to discharge through a complicated arrangement of distributary channels, obstructed by falls and rapids.
The region through which these rivers flow has a nearly featureless surface, slightly tilted upward toward the north and the east. South‐ward the nearly flat surface may be followed along the eastern shore of the bay, and southwestward the rock surface continues to sink below the level of the lake at the rate of about 12 feet to the mile. This continues for about 60 . . .
