Not exactly. The concrete spillway is the only controlled spillway. The
emergency spillway is, as mentioned, to the left. It's referred to as the emergency spillway because it comes into play only when the level of the lake is unable to be lowered by the concrete spillway and the discharge at bottom of the dam. It functions because the rim is lower than the top of the dam and water is released with no human intervention. In short, in an emergency, the lake overflows beginning at the emergency spillway instead of the dam itself.
