The Groundwater Ambient Monitoring and Assessment Program (GAMA) is an all-inclusive monitoring program for groundwater that was implemented in 2000 in California, United States. It was created by the California State Water Resources Control Board as an improvement from groundwater programs that were already in place.
While the volume of groundwater in California is very large, aquifers can be over drafted when groundwater is removed more rapidly than it is replenished. In 1999, it was estimated that the average, annual overdrafting was around 2,200,000 acre-feet (2.7 km 3 ) across the state, with 800,000 acre-feet (0.99 km 3 ) in the Central Valley.
Temperature data from monitoring wells indicate that horizontal groundwater flow occurs primarily above 775 feet (236 m) in southern-central regions and above 510 feet (160 m) in southeastern areas. [7]
In a new study, scientists begin to map underground channels that are optimal areas for recharging California's groundwater in the Central Valley.
California's groundwater levels rose significantly in 2023, one of the wettest years in decades. State officials say efforts to replenish aquifers helped.
Weather. 24/7 Help. ... While no one knows the exact amount of water that can be stored within California’s 515 groundwater basins, DWR estimates the total storage capacity at somewhere between ...
Groundwater recharge projects are expected to increase in number in future years throughout California due to the comparatively low cost and massive storage capabilities of aquifers. The total volume of groundwater capacity is estimated to be 850 million acre-feet, while there is only around 50 million acre-feet of available surface freshwater ...
After massive downpours flooded California’s rivers and packed mountains with snow, the state reported Monday the first increase in groundwater supplies in four years. The state saw 4.1 million ...
