Hoover Dam. Hoover Dam, formerly called Boulder Dam, dam in Black Canyon on the Colorado River, at the Arizona-Nevada border, U.S. Constructed between 1930 and 1936, it is the highest concrete arch dam in the United States. It impounds Lake Mead, which extends for 115 miles (185 km) upstream and is one of the largest manmade lakes in the world.
It is the second largest state reservoir in northern California, with more than 167 miles of shoreline. Oroville Dam is the tallest dam in the United States, measuring 770 feet high â 44 feet taller than Hoover Dam â and 6,920 feet across. The lake is located where the North, Middle, and South Forks, and the West Branches of the Feather River join.
