By the early 20th century, Californian cities as far south as Los Angeles were looking to new sources for electricity because of their rapidly growing populations and industries. Two visionaries, railroad baron Henry E. Huntington and engineer John S. Eastwood established a fledgling power company in 1902 today known as Southern California Edison, and acquired water rights to the upper San Joaquin River from the Miller and Lux Corporation. During that year, Huntington and Eastwood devised plans to utilize the water of the San Joaquin River and some of its headwaters tributaries in what would become one of the most extensive hydroelectric systems in the world, known as the Big Creek Hydroelectric Project.
