Check out Lake Berryessa!

First the rain, now the drain. California’s punishing rain this month has flooded neighborhoods and triggered evacuations. It has also pushed Lake Berryessa in Napa County way beyond capacity, pouring water into its bathtub-like drain. It’s the first time that’s happened in 11 years, reports CBS News correspondent Mireya Villarreal.

“Back in October, we were essentially half-full,” said Roland Sanford, general manager of the Solano County Water Agency. “This is the first time that the lake has been so low, and filled-up and spilled in one year.” What looks calm at the top of the “Morning Glory Spillway” looks like a raging torrent at the bottom.

The spillway is located 200 feet from the Monticello Dam. It is shaped like a funnel, 72-feet wide at its lip and narrowing to 28 feet at an outlet down at the Putah Creek. When water in the lake rises to more than 440 feet above sea level, it spills over the lip of a funnel and pours into the creek 700 feet below. 

When the reservoir reaches capacity, this spillway can take in about 48,000 cubic feet of water per second. That’s the equivalent of draining half of an Olympic sized pool in one second.
