The Harbor Bay Isle lagoon is located on the Bay Farm Island peninsula in Alameda, on the east bay shoreline north of the Oakland Metropolitan Airport. It forms the major component of the Harbor Bay Isle Master Plan Community, providing open space, wildlife habitat, aesthetic and recreational enjoyment for the residents of the Community. The lagoon also accepts storm water drainage from the adjacent developed areas.

Extending from San Francisco Bay at the west end of the lagoon system to San Leandro channel at the north, the lagoon is a narrow river like waterway nearly 2.5 miles long. The basic operation of the Lagoon is dependent upon the normal San Francisco Bay tidal action which through a series of sluice gates at each end of the lagoon, provide a degree of flushing from west to north while maintaining a calibrated water level 2 to 4 inches below the top of curb. During normal operation, the anticipated average water retention time is approximately four days.

The Community Water Quality Division is dedicated in providing a safe and positive environment for our residents to enjoy. Please take a moment to review this NEW, dedicated Lagoon informational web page intended to provide information to our Harbor Bay Isle residents regarding our Best Management Practice for Lagoon water quality and establish an avenue of information readily available for homeowners.
