Upper Klamath Lake, Oregon's largest body of water at about 90,000 acres, sustained Indians inhabiting its shores, the "People of the Lake," who lived well on wild fowl, fish, and wocus seeds. The first known white visitors in 1825-26 were Hudson's Bay trappers under Tom McKay and Finan McDonald. In 1846, while exploring there, John C. Fremont received news of the war with Mexico, which caused him to hasten around the northern end and back to California, where he played a part in the acquisition of that state. The lake now serves as a natural reservoir for the Klamath Reclamation project, for logging operations, and for Klamath River power plants, and it remains a resort for fishermen and a haven for wild life.
