Upper Klamath Lake, Oregon's largest body of water at about 90,000 acres, sustained Indians living along 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 John C. Fremont, exploring here, received news of the war with Mexico, prompting him to hasten around the northern end and back to California, where he took 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 wildlife.
