A pathway for excess water to exit a pond or lake. Spillways are designed to maintain the water level under normal inflows from snow melt, spring flow and rain. They are also called overflows. There are two types of spillways: Principal and Emergency.

Principal SpillwayThe principal spillway is responsible for maintaining the pond water at a desired level. Whenever water enters the pond and the level rises, water first exits the pond through this spillway. They are typically constructed out of pipe (metal, plastic or concrete) or any type of concrete structure.
Emergency SpillwayThe emergency spillway is responsible for protecting the dam. Whenever so much water enters the pond and the principal spillway cannot carry it all out of the pond, the emergency spillway provides a stable pathway for the excess water to flow around and not over the top of the dam. If water were to flow over the top of the dam, it can begin to erode the structure quickly causing a total dam failure and potentially causing significant property damage downstream.
