Angwin's Water Supply

Many parts of Northern California, including the Napa Valley, experience water shortages during periods of less-than-normal rainfall.  Angwin is not immune to these dry periods.  During any year in which less than 25 inches of rain falls on the community Angwinites can expect to see some wells run close to dry, and water levels in lakes and reservoirs fall considerably.  The wise planner sinks a deep well in Angwin if he/she does not receive water from one of the community's water systems.

Some 460 families in the Angwin and nearby Deer Park village get their water from the Howell Mountain Mutual Water Company.  The company is owned by its users.  Its water supply comes from the rainfall onto thousands of acres of watershed of Bell Canyon and is gathered into nine man-made reservoirs.  The reservoirs are formed by dams that hold water of the reservoirs. 

The water company is the largest water system in Angwin and is directed by a Board of Directors who carefully watch the safety of the dams, pipe lines and other parts of the operation.

A second, large water system in Angwin is operated by Pacific Union College.  It supplies water to not only the beautiful campus of the school, but also to a number of off-campus homes of faculty and staff members.  The system is fed by several wells which have served the college for many years.

A number of other small, mutual water companies serve Angwin.  Among these is the Rancho La Jota system, the Linda Falls Terrace system, the Crestmont system and the La Tierra Heights Mutual Water Company.  All together these systems serve approximately 80 homes.

The rest of the Angwin community of some 3,500 persons relies on individual wells for its water supply.
