Hoover Dam - Construction

UNLV Special Collections

Diversion Tunnel No. 3 on the Arizona Side of Hoover Dam is shown under construction. The Hoover Dam sits in between Nevada and Arizona and divides the Colorado River. The project is built to help keep silt and sediment out of the Colorado River, and functions as a power plant as well as a dam. The reservoir behind the dam creates Lake Mead.
