The Central Valley in California subsides when groundwater is pumped faster than underground aquifers can be recharged. The Central Valley has been sinking at differing rates since the 1920s and is estimated to have sunk up to 28 feet. [1] During drought years, the valley is prone to accelerated subsidence due to groundwater extraction.
The first recorded case of land subsidence was in the 1940s. Land subsidence can be as little as local land collapsing or as large as an entire region's land being lowered. The subsidence can lead to infrastructural and ecosystem damage. Lowering of the water table, which makes water harder to reach streams and rivers
In 1949 he served as the district geologist. He headed the project to delineate and calculate the storage capacity of California's aquifer systems. This work was essential to the creation of the California Water Plan. [1] In 1956 he led a survey to investigate aquifer mechanics and the causes of land subsidence in Sacramento, California. [5]

The Jurupa Oak, or Hurungna Oak, [1] [2] is a clonal colony of Quercus palmeri (Palmer's oak) trees in the Jurupa Mountains in Crestmore Heights, Riverside County, California. The colony has survived an estimated 13,000 years through clonal reproduction, [ 3 ] [ 4 ] [ 5 ] making it one of the world's oldest living trees . [ 5 ]
