What is a watershed? A subwatershed?

A watershed is the land area or topographic region that drains into a particular stream, river, or lake. This land feature can be identified by tracing a line on a map along the highest elevations between two areas.

Large watersheds may contain hundreds or thousands of smaller subwatersheds that drain into the river or other waterbody. The Brazos River watershed encompasses more than 42,000 square miles and includes many smaller streams and rivers with their own smaller watersheds.




The information provided on this site is intended as background on water within the Brazos River basin. There should be no expectation that this information is all encompassing, complete or in any way examines every aspect of this very complex natural resource.
