The
Pomona Valley Protective Association (PVPA) was initially established
in 1909 by way of a mutual agreement between the major water interests
in the greater Pomona Valley. PVPA was formed to protect the rights
of the water users in the Claremont, Pomona, Upland, and La Verne
areas from outside interests developing and exporting local water
from the area, to protect the rights of its stockholders and to
insure an ongoing supply of water to the Pomona Valley. A nine
member Board of Directors, elected annually at the stockholder’s
meeting, governs the Association. |

| There
are six groundwater basins recharged by the activities of PVPA:
the Canyon, Upper and Lower Claremont Heights, Live Oak, Pomona
and Ganesha Basins. Together they make up the area known as “The
Six Basins.”
Water development
in the area began in the mid-1800. This development included the
diversion of the surface flow from the local creeks, springs and
Cienegas for agricultural use. As the area became more populated,
the natural sources became overtaxed. In the late 1800’s,
wells were dug in the Cienegas and tunnels were dug to intercept
subsurface water. Pumps were installed in the wells when water
levels became too low to flow by gravity. |

Activities of the PVPA and others
to conserve the native surface water by recharging the ground
water basins became an important aspect of early water management.
Subsequent growth and urbanization eventually led to the importation
of water to meet the additional water demands of the area.
In 1998 PVPA, the groundwater producers
in the Pomona Valley and others entered into a stipulated judgment
in the case: Southern California Water Company v. City of La
Verne at al, Case No. KC029152, County of Los Angeles, State
of California. This judgment allocated the rights of producers
and appointed a Watermaster to oversee the operation of the
basins. PVPA currently engages in water conservation activities
in these basins under the general direction of the Six Basins
Watermaster.
