It was to have been {{convert|813|ft|m}} high and was to be located {{convert|12|mi|km}} upstream of the river's mouth. It would stand almost as tall as the Transamerica Pyramid building in San Francisco, but would be much more massive. It would flood {{convert|40|mi|km}} of the Trinity River, including the Yurok, Karuk and Hupa Indian Reservations, the lower Salmon River, and {{convert|70|mi|km}} of the Klamath River, creating a reservoir with a volume of {{convert|15000000|acre.ft|km3}} – two-thirds of the size of Lake Mead, and becoming the largest reservoir in California. The water would flow by gravity through a tunnel {{convert|60|mi|km}} long to the Sacramento River just above Redding and onward to Southern California, in an extreme diversion plan known as the Klamath Diversion. The tunnel would have been located near the southernmost extent of the reservoir. It was named in the language of the Yurok people. References
