A watershed is an area of land that contains streams and rivers that all drain into a single body of water, such as a lake or the ocean. Watersheds can be big or small, but they all have high points like ridges and mountains that capture water, store it, and eventually release it downhill. Many of our actions impact watersheds, and as the rivers and streams flow downstream through communities, the ocean becomes the final resting place for much of the pollution and contaminants that these rivers and streams are carrying.
