The Intake Structure is 249 feet tall, 540 feet long and 170 feet wide. Its purpose is to house the necessary hoisting equipment, gates and auxiliary equipment for the five penstocks and three regulatory tunnels. Each of the five penstocks are 24 feet in diameter and convey water to the turbines for power generation. The three regulatory tunnels send water downstream for the purpose of flood control.
The purpose of the penstocks is to carry water
from the Intake to the scroll case around the
turbine. Water moves through the penstocks at a
rate of 60,000 gallons per second and at a speed
of 12 to 13 miles per hour.
