Hoover Dam is a major tourist attraction, with 7 million tourists a year. Officials eventually decided on a massive concrete arch-gravity dam, the design of which was overseen by the Bureau's chief design engineer John L. Savage. The maximum net generation was 10.348 TWh in 1984, and the minimum since 1940 was 2.648 TWh in 1956. GAGE - Stage recorder. This initial design was criticized by many as being too plain and unremarkable for a project of such immense scale, so Los Angeles-based architect Gordon B. Kaufmann, then the supervising architect to the Bureau of Reclamation, was brought in to redesign the exteriors. Image of the Day Water. [51] The inner tunnels' outlets are equipped with gates that can be closed to drain the tunnels for maintenance. The buckets were then suspended from aerial cableways which were used to deliver the bucket to a specific column.

Lake Mead is the largest reservoir in the United States and part of a system that supplies water to at least 40 million people across seven states and northern Mexico. Title: USGS Current Water Data for Nevada [106][107], In 2018, the Los Angeles Department of Water and Power (LADWP) proposed a $3 billion pumped-storage hydroelectricity projecta "battery" of sortsthat would use wind and solar power to recirculate water back up to Lake Mead from a pumping station 20 miles (32km) downriver. Burbank, CA - 0.5876 percent Both times, when inspecting the tunnels after the spillways were used, engineers found major damage to the concrete linings and underlying rock. [108][109][110], Electricity from the dam's powerhouse was originally sold pursuant to a fifty-year contract, authorized by Congress in 1934, which ran from 1937 to 1987. In recent years the water levels at the Hoover Dam and Lake Mead have fallen far below historical norms. Colorado River Drought Contingency Planning. Edison allowed land options it held on the river to lapseincluding an option for what became the site of Hoover Dam.
