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 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.
