It would have been taller than any existing dam in the United States and it would stand almost as tall as the Transamerica Pyramid building in San Francisco, but would have been much more massive. It would have flooded 40 miles (64 km) of the Trinity River, including the Yurok, Karuk and Hupa Indian Reservations, the lower Salmon River, and 70 miles (110 km) of the Klamath River, creating a reservoir with a volume of 15,000,000 acre-feet (19 km³) – three fifths the size of Lake Mead, and over three times the size of the current largest reservoir in California, Shasta Lake. The water would flow by gravity through a tunnel 60 miles (97 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.
