A spillway for the lake and Monticello Dam. When water levels rise above 440 feet, water starts spilling down the hole and into Putah Creek, hundreds of feet below.The opportunity to see it in action, draws thousands of people to the southern end of Lake Berryessa. Best seen during the rainy season when the lake is full.
Near the dam on the southeast side of the reservoir is an open bell-mouth spillway, 72 feet (22 m) in diameter, which is known as the Glory Hole. The pipe has a straight drop of 200 feet (61 m), and the diameter shrinks down to about 28 feet (8.5 m). The spillway has a maximum capacity of 48,000 cfs (1360 m³/s).
