California focuses on increasing groundwater data but needs major infrastructure projects

Governor Gavin Newsom and the California Department of Water Resources (DWR) have released a report indicating increased groundwater data collection in California. This initiative aims to strengthen partnerships with water agencies, though it falls short of fully preparing the state for future climatic challenges.

Governor Newsom emphasized the need for comprehensive water infrastructure improvements, stating, “California is taking an all-in approach to its water supply — including creating more groundwater storage and data to help us plan for the future. The data doesn’t lie, and it is telling us that our water system is unprepared for California’s hotter and drier climate. That means we also need to build new water infrastructure like the Delta Conveyance Project. We literally cannot afford to wait to complete this vital project and Californians are sick and tired of the self-imposed roadblocks standing in the way of our state’s continued progress.”

The report reveals that groundwater storage increased by 2.2 million acre-feet during Water Year 2024 due to precipitation and efforts by state and regional partners. These efforts include capturing high flows during winter storms, expanding recharge basins, improving monitoring, and coordinating among local agencies.

Despite these gains, California lacks sufficient infrastructure for long-term water sustainability in a changing climate. The Delta Conveyance Project is highlighted as a critical initiative needing advancement.

Groundwater data from DWR's Semi-Annual Groundwater Conditions Update will aid in managing groundwater basins more effectively. This information supports groundwater recharge efforts directed by Governor Newsom.

In addition, ongoing partnerships through the LandFlex program aim to enhance groundwater storage by working with farmers. DWR has awarded $23.3 million in grants to six Central Valley agencies to assist farms in transitioning towards sustainable practices while conserving drinking water supplies.

The modernization of California's water delivery systems remains crucial for future readiness. Governor Newsom urges legislative support for fast-tracking the Delta Conveyance Project, which could improve high-flow capture capabilities during storm events and mitigate earthquake risks.

Without these advancements, reliable delivery of water across homes, farms, and businesses may be compromised as climate conditions evolve.
