In the 1920s the City of Los Angeles proposed the Tehipite Valley as the site of a hydroelectric dam. This was one of the key controversies before, and for many years after the establishment of Kings Canyon National Park. The initial dedication of the park on March 4, 1940 by President Franklin D. Roosevelt did not include Tehipite Valley; it was not until 1965 when Tehipite Valley and Cedar Grove were finally added to the park, making them forever off-limits to industrial development.
