[4] [11] The California Sustainable Groundwater Management Act of 2014 was the first to specify how to manage groundwater in a way that would not harm or endanger future access to clean groundwater. [2] Before this act, no regulations governed groundwater management other than the federal Safe Drinking Water Act and Clean Water Act. These acts ...
California has had a long history of complex water rights dealing with the ownership and management of surface water. Groundwater has stayed under the regulation radar, which led to the overdraft of vital basins and the subsidence of land taking place throughout the Central Valley. The SGMA gives responsibility to both state authority and local ...
Farmers use a combination of surface water and groundwater for irrigation. During drought years there is less surface water being provided to farmers and they rely on pumping more groundwater. In California, there is a hierarchy of water entitlement in which those with water rights have precedence to receive and use surface water. [2]
To meet the lofty goals of California’s 2014 Sustainable Groundwater Management Act, the authors estimated that users statewide will need to reduce groundwater pumping by about 19.2 percent by ...
California created an orchard for the world in large part by tapping into prehistoric aquifers that underlay the Central Valley. Much of that water is now gone , never to fully return.
With long-term declines in groundwater levels putting thousands of domestic wells at risk and causing the ground to sink in parts of the San Joaquin Valley, state regulators are moving forward ...
In California, groundwater accounts for around 41% of the state's total water supply, [1] although this number varies between wet and dry years. During years of greater than average rainfall, less groundwater is used to allow for reserves to be available during dry years. Up to 60% of all water can be sourced from groundwater during dry years.
The law was based on the idea that groundwater could best be managed at the local level, and it called for newly formed local agencies to gradually adopt measures to address chronic declines in ...
