Nipigon Lake
Discovered by Charles de Greysolon, Sieur de La
Tourette, brother of Du Lhut, about 1678. Built several trading-posts on
or near the lake, between 1678 and 1686. La Verendrye had charge of
these forts in 1727-1728, and acquired there much of the information
which induced him to undertake his long search for the Western Sea. In
1784 Edouard Umfreville was sent by the North West Company to discover a
canoe route from the lake west to the Winnipeg River. The narrative of
his successful expedition is in the archives of McGill University.
