State Water Project – Water Quality Data
The District obtains virtually all of its water supply from the California Aqueduct of the State Water Project (SWP). Use the links below to obtain SWP water quality data.  Note that water quality can vary significantly from month to month and year to year.  For example, salt content (EC) is lower in spring than in the fall and lower in wet water years than dry water years.  The Engineering Department can provide assistance upon request.

The closest SWP sampling points to the District are:
