What is a Watershed?

Everyone lives in a watershed. A watershed is an area of land that drains into a stream, lake, or river.  For small creeks or streams this can be just a small area. For example, within the City of Roanoke there are many different watersheds that feed into the Roanoke River. However, the whole Roanoke River watershed crosses multiple cities and even the state boundary and empties into Albemarle Sound. This makes the quality and health of watersheds difficult to manage as they cover such large areas and cross into different governing bodies. 

Using the map below, type your address to find your watershed, then click on the map for more details. Are you able to find where the Roanoke River starts (the source) and where it finally drains into the sound (the mouth)?
