Check out this spillway in action at Lake Berryessa in Napa County California. As you may already know, California is receiving an atmospheric river of precipitation. The spillway on this dam kicks in like a bathtub drain. The outlet is at the bottom of the dam to the Putah creek. It looks like they needed to build the spillway this way because of the terrain on both sides of the dam. It’s a really innovative solution, very dramatic and mesmerizing when the water reaches the spillway elevation. These design engineers get style points! Check out the video and article below.
