California's Central Valley covers about 20,000 square miles and is one of the most productive agricultural regions in the world. The aquifer system is divided into three subregions on the basis of surface-water basins. In areas adjacent to the Delta-Mendota Canal (DMC), extensive groundwater withdrawal from the San Joaquin Valley aquifer system has caused areas of the ground to sink as much as 10 feet, a process known as land subsidence.

The Latest News and Updates in usgs brought to you by the team at YourCentralValley.com: July 8, 2009 For Immediate Release. Scientists developed the geologic texture model to describe the coarseness or fineness of valley-fill materials that make up the aquifer system, and then used it to estimate hydraulic properties for every cell in the model grid. Combined with the Farm Process, MODFLOW simulates natural and human-induced water movement and consumption over the landscape and accounts for supply-constrained and demand-driven conjunctive use of surface and groundwater in agricultural, urban, and natural settings. We created the first Central Valley-wide time series maps of MSS plant distributions and productivity. The CVHM was constrained by comparing simulated and historically observed groundwater levels, streamflows, and subsidence. Central Valley median house value is $204,200 in 2000. The Central Valley, also known as the Great Valley of California, covers about 20,000 square miles and is one of the more notable structural depressions in the world. The Central Valley of California contains the largest basin-fill aquifer system in Segment 1. As of 2000, the total Central Valley population is 1,857.
