An annual analysis of groundwater levels shows significant increases over the past 10 years throughout most of the Coachella Valley.
The two annual reports for the 2017-18 water year, one on the Indio Subbasin and the other on the Mission Creek Subbasin, which make up most of the valley’s aquifer, were submitted before the State’s April 1 deadline.
Successful groundwater replenishment programs along with continued efforts to conserve, reduce water waste and to connect customers to the nonpotable water system for irrigation purposes resulted in the positive trends observed in groundwater storage in both subbasins during the past 10 years.
The Indio Subbasin is located under the cities of Palm Springs, Cathedral City, Rancho Mirage, Palm Desert, Indian Wells, La Quinta, Indio, and Coachella, and the unincorporated communities of Thousand Palms, Thermal, Bermuda Dunes, Oasis, and Mecca.
The Indio Subbasin report shows that over the past ten years there were significant increases in groundwater levels in most of the subbasin in the range of 2-50 feet. These gains highlight the progress towards long-term sustainable management of the subbasin.
The Mission Creek Subbasin is located under Desert Hot Springs and the unincorporated area of Indio Hills.
This subbasin also shows that over the past 10 years there were significant increases in groundwater levels in most of the subbasin of up to 28.5 feet. The subbasin shows positive trends since 2005 for future sustainability.
There were localized portions of decreased water levels in the range of 2-8 feet in the mid-valley area of the Indio Subbasin. This area will soon benefit from the Coachella Valley Water District’s (CVWD) Palm Desert Replenishment Facility. Phase one of the project is operational and phase two planning is underway.
CVWD is also continuing efforts to connect more golf courses to nonpotable water such as recycled or Colorado River water instead of groundwater.
The Annual Reports were submitted to the California Department of Water Resources to comply with the reporting requirements of the Sustainable Groundwater Management Act. To read the full reports, visit cvwd.org/sgma.
The Coachella Valley Water District is a public agency governed by a five-member board of directors. The district provides domestic and irrigation water, agricultural drainage, wastewater treatment and reclamation services, regional storm water protection, groundwater management and water conservation. It serves approximately 108,000 residential and business customers across 1,000 square miles, located primarily in Riverside County, but also in portions of Imperial and San Diego counties.
