The Hoover Dam is a large dam on the Colorado River. It is on the border of the states of Arizona and Nevada. The reservoir it made is called Lake Mead. The dam is named after the former US President Herbert Hoover. At first it was called "Boulder Dam", but the name was changed to honor Hoover, who was president when the idea of building the dam started.
