A modest bump in the allocation of water being released from Northern California will make billions of additional gallons available to Southern California water agencies, according to. Population growth, a changing climate, and increasing costs are straining California’s extensive water supply system, requiring new strategies to manage demand and diversify water sources. An urban water supplier that relies on imported water from the State Water Project or the Bureau of Reclamation shall submit its annual water supply and demand assessment within 14 days of receiving its final allocations, or by July 1 of each year, whichever is later. A modest bump in the allocation of water being released from Northern California will make billions of additional gallons available to Southern California water agencies, according to state and local experts. A coalition of environmental groups is calling for a ‘water renaissance’ in Southern California cities, saying the region needs to invest in getting more of its water locally. An urban water supplier that relies on imported water from the State Water Project or the Bureau of Reclamation shall submit its annual water supply and demand assessment within 14 days of receiving its final allocations, or by July 1 of each year, whichever is later. From 2020 to 2023, in response to drought conditions, the State Water Board adopted emergency regulations and developed tools and information to further understand water availability in key watersheds. At stake are the rules that guide operation of the federal Central Valley Project and State Water Project, the two systems that deliver water from Northern California rivers to San Joaquin. FACT: Most of Southern California’s water does not come from Northern California. In fact, Southern California gets roughly a third of its water from Northern California, a third from the Colorado River, and a third from local sources. A growing coalition of conservationists is now pushing a provocative, ambitious vision: they argue that Southern California could meet 85% of its water needs through local resources, effectively bypassing the need for massive, controversial infrastructure projects like the proposed Delta tunnel.
