Our Water
Click to EnlargeIn the 1950’s, faced with drought conditions and the devastating impacts that it would have on the agricultural community, the Vista Irrigation District had to look for additional water sources to supplement its local source from Lake Henshaw. In February 1954, the district's board of directors made the decision to join the San Diego County Water Authority so that it could receive imported water from northern California and the Colorado River. This decision has helped the district meet its customers’ needs for a reliable supply during dry conditions then and now.

Customers of the district have historically enjoyed the ability to get inexpensive, reliable water from a local source. In this regard, district customers differ from most San Diego County residents, who must rely exclusively on imported water from outside the county. As noted above, the district is also able, as needed, to receive imported water; however, local water from Lake Henshaw has supplied about one-half of our customers’ needs since the mid 1950’s.

In a normal rainfall year, the surrounding 200 square miles of watershed produce enough runoff into the lake to supply more than half of the district's needs. However, during extended dry periods when there is little or no run-off and minimal groundwater replenishment, over 80% of the total water supplied to customers comes from imported sources.

While the board's decision to join the Water Authority in the 1950’s was somewhat controversial at the time, their action enabled future customers the assurance of a reliable and sustainable water supply. The availability of local as well as imported water has provided the district with the flexibility it needs to serve customers with little or no interruption.
