Here is the dam on the right, the main spillway, the emergency spillway, which is a concrete spillway barely visible but in between the main spillway and the parking lot. The main areas of concern are that the water is so high right now it has flooded the parking lot to the left and is spilling over the hillside from there. This is not reinforced by concrete, it is just packed dirt, and is not considered part of the containment. The water is strong enough to erode this area quickly, and so it will erode a pathway around and maybe under the cement emergency spillway. Fortunately though, this will not affect the main dam, which is why they are only forecasting the top 30 ft. of water from the lake to be released.
