Water Intake Towers at the Hoover Dam

Intakes are towered structures that stand in and around the center of a dam. Intakes regulate the supply of water that is required for powerplant turbines. They are usually made of reinforced concrete and steel.

One of the most famous sets of intakes in the world, located in Hoover Dam, consists of an 82-foot (25-m) diameter base, and a 63-foot, three-inch (19.2-m, 7.6-cm) diameter on the top. Each of the four towers reaches as high as 395 feet (120.4 m) and consists of 93,674 cubic yards (71,619 m³) of concrete and 15,299,604 pounds (6.9 million kg) of steel.^[1]
