1967 Map of Namakan Island

About this map

Namakan Lake dominates this borderland landscape, where the international boundary between the United States and Canada threads through a complex archipelago. In the late 1960s, this region remained a wilderness of water and forest, characterized by the Superior National Forest and the intricate channels of the Canadian Channel. The map documents a regulated hydraulic environment, noting a normal reservoir pool elevation of 1119 feet maintained by structures like the Kettle Falls Dam and the Squirrel Falls Dam.
