San Pasqual Valley Groundwater Basin

Basin Description ( 9-10 )
The San Pasqual Valley Groundwater Basin, shown on the above map, underlies San Pasqual Valley and Cloverdale, Rockwood, and Bandy Canyons in central San Diego County. Santa Ysabel, Guejito, and Santa Maria Creeks drain the valley and converge to form the San Dieguito River, which flows into Lake Hodges.

Data Management System (DMS)
The San Pasqual Valley DMS stores and reports information relevant to GSP implementation and monitoring of the Basin. The DMS (called Opti) [see User Guide] provides historical groundwater level measurements, groundwater quality measurements, and stream flow measurements used in GSP development. Annual monitoring data will be uploaded into Opti with each Annual Report.

Due to the COVID-19 public health emergency, the County of San Diego is making several changes related to public meetings to protect the public's health and prevent the disease from spreading.

As of January 7, 2022, public meetings will be conducted pursuant to the provisions of California Government Code Section 54953(e), added by Assembly Bill 361, which allows the County to use teleconferencing and to provide the public an opportunity to address county staff via a call-in option.
