What are watersheds, and how many are there in Harris County?
Basically, a watershed is a land area that ultimately drains rainfall runoff (or stormwater) to a common outlet point – typically a body of water, which is mostly creeks and bayous in Harris County. You’re sitting in a watershed now. For example, if you live in the Brays Bayou watershed, the rain that falls on your house will eventually end up in Brays Bayou. Watershed boundaries are formed by nature and are largely determined by the topography or “lay of the land.” Harris County has 22 major watersheds that each drain into 22 major waterways, each with its own independent flooding issues.
