Why Watersheds?

Everyone lives in a watershed -- the land that water flows over or through on its way to a creek, delta, bay, or ocean. Everything that happens in the watershed affects water quality and habitat quality for fish, birds and other living things. Pollution in distant parts of a watershed can be washed into storm drains, and cause problems downstream.
