Twenty years ago, in October 2003, water officials from across the Southwest signed the largest water conservation-and-transfer agreement in U.S. history, the QSA, or Quantification Settlement Agreement. The agreement has provided decades of water security for San Diego County and benefits for numerous partners across the Southwest. In total, that pact supplies more than half […]
Thanks to a decades-long supply diversification strategy and continued efficient use of water across the region, the San Diego County Water Authority announced that the region has reliable supplies to meet demands in Water Year 2024, which started October 1. Hydrologists use Oct. 1 to begin measuring the snow and rain that will help carry […]
The cutting-edge world of desalination and the future of water supply in Southern California is the topic for conversation and insight from water agency officials in a new podcast.

The East County Advanced Water Purification project is progressing, with construction underway at multiple East San Diego County locations. The project will create a new, local, sustainable, and drought-proof water supply using state-of-the-art technology to purify East San Diego County’s recycled water. Construction for the East County AWP is expected to be completed in 2025, […]
Construction on the City of Poway’s clearwell replacement is anticipated to begin this fall following the award of contract to Gateway Pacific Contractors, Inc. The contract was awarded at the Sept. 19 Poway City Council meeting. The clearwell is Poway’s major storage reservoir for water treated at the water treatment plant, prior to being distributed […]
El Niño is anticipated to continue through the Northern Hemisphere winter (with a greater than 95% chance through January – March 2024). An El Niño Advisory remains in effect. In August, sea surface temperatures (SSTs) were above average across the equatorial Pacific Ocean [Fig. 1], with strengthening in the central and east-central Pacific. All of the […]
A new but little-known change in California law designating aquifers as “natural infrastructure” promises to unleash a flood of public funding for projects that increase the state’s supply of groundwater. The change is buried in a sweeping state budget-related law, enacted in July, that also makes it easier for property owners and water managers to […]
Legislation signed into law by California Governor Gavin Newsom ensures the state has the science and weather forecasting tools it needs for more flexible reservoir operations. The bill, AB 30, makes breakthrough water management technology standard for the California Department of Water Resources.

Water recycling reduces the need to import or develop additional drinking water supplies. It is a vital water management strategy to ensure a safe, reliable, and locally controlled water supply to support healthy environments, robust economies, and high quality of life. Water and wastewater agencies in San Diego County are developing or expanding their water […]
The long-running debate over whether the Fallbrook and Rainbow communities should leave the San Diego County Water Authority to obtain cheaper rates ignores a very large elephant in the room — climate change. If the two rural communities cast their lot with Riverside County, their agricultural economy will depend upon the Colorado River and the State Water Project, both of […]
The Bureau of Reclamation on August 15, released the Colorado River Basin August 2023 24-Month Study, which determines the tiers for the coordinated operation of Lake Powell and Lake Mead for 2024.

The start of wine grape growing season in California’s Napa Valley now comes nearly a month earlier than it used to because of the region’s warming climate, according to a new study from a team led by UC San Diego Scripps Institution of Oceanography researcher Dan Cayan. The research, published online in the International Journal of […]
Across the western U.S., many areas received record or near-record amounts of snowpack over the winter. With the spring and summer temperatures melting the abundant snow, a record volume of streamflow has been recorded in several basins in the southwestern U.S., providing more water for the area later into the summer than is typically seen.
