Typically, the main pond exit is a pipe while the emergency spillway is an open area higher than the primary overflow but below to of the top of the dam that is located beyond the dam on a gentle slope to avoid erosion. The emergency spillway is intended to carry much larger volumes of water than the primary spillway but gets used infrequently.
