California aquifers, excerpted from map in Ground Water Atlas of the United States (USGS, 2000): Lavender is "other" for "rocks that generally yield less than 10 gal/min to wells"; dark green-blue (3) are the California coastal basin aquifers, bright-turquoise blue (7) is the Central Valley aquifer system, flat cobalt-blue (1) down south is Basin and Range aquifers
[3] [4] As a result, investment into groundwater recharge basins has been steadily increasing in recent years. Groundwater projects are planned to provide an increase of 500,000 acre-feet annually to the water supply. [5] With 2023 being an extreme wet year, California achieved a record-setting 8.7 million acre-feet of groundwater to aquifers. [6]
California groundwater basins, subbasins, and hydrologic regions. The California Department of Water Resources recognizes 10 hydrologic regions and three additional drainage areas within the U.S. state of California. The hydrologic regions are further subdivided into 515 groundwater basins. [1]
In the early parts of the 20th century, the Santa Clara Valley was a vegetable and fruit growing region. Ground water was pumped heavily, leading to the Santa Clara valley being the first region recognized to be affected by land subsidence in the 1940s. [2] Between 1912 and 1966, artesian pressure levels dropped more than 200 feet (61 m).
California passed its landmark groundwater law in 2014. The goals of sustainable management remain a long way off. Despite California groundwater law, aquifers keep dropping in a 'race to the bottom'
