Introduction to Watersheds of Orange County,
What is a Watershed?
"That area of land, a bounded hydrologic system, within
which all living things are inextricably linked by their common water course and where,
as humans settled, simple logic demanded that they become part of the community."
John Wesley Powell
A watershed is the geographic area draining into a river system, ocean
or other body of water through a single outlet and includes the receiving waters. Watersheds
are usually bordered, and separated from other watersheds, by mountain ridges or other naturally
In Orange County,
there are 13 watersheds. We've provided a page specifically about
the coast as well. In this section you'll find reports, studies,
grants, projects, and regulations specific to each watershed. A
variety of maps are also available displaying drainageways and land
elevations; city boundaries; and land use. For committees and public
forums that meet on specific topics, you'll find meeting notices
and agendas. You may subscribe for a particular meeting and receive
email notification of meetings.
