Briefings
California is preparing for a potential El Niño event that could bring record rainfall, prompting a strategic shift toward underground storage. The state has passed the Sustainable Groundwater Management Act to manage aquifers, which currently hold 21 million acre-feet of water. Experts note that while reservoirs can hold this volume, the land could theoretically hold a billion acre-feet underground. The primary strategy involves diverting excess rainfall into basins to recharge aquifers, which then provide 40% of the state's supply during droughts. This approach aims to reduce reliance on imported water and restore wetlands, though the timing of storms remains a critical operational challenge.
Key points
- California passed the Sustainable Groundwater Management Act in 2014 to manage declining aquifers, requiring local agencies to tackle subterranean water crises.
- The state's major reservoirs currently hold 21 million acre-feet of water, but the land could hold a billion acre-feet underground if managed correctly.
Context
California faces a climate transition between drought and intense rain, with the state renegotiating its relationship with precipitation. The Central Valley's agricultural reliance on groundwater is causing land subsidence, while wetlands have been lost. This article details the state's plan to use managed aquifer recharge to store flood flows underground, potentially expanding water capacity and restoring ecosystems.
Limitations
Evidence covers only California's response to a hypothetical El Niño event, not historical data or future forecasts. Specific dates for the El Niño event are not provided, and the exact timing of the upcoming storm is unknown.
