The South Coast Hydrologic Subregion is composed of three third-level hydrological units. The federally-defined Southern California Coastal water resource subregion equates roughly with the state-designated South Coast hydrologic region. Per a USGS report of 1976, "Water deficiency is prevalent in the South Coastal subregion."
Map of water storage and delivery facilities as well as major rivers and cities in the state of California. Central Valley Project systems are in red, and State Water Project in blue. California's interconnected water system serves almost 40 million people and irrigates over 5,680,000 acres (2,300,000 ha) of farmland. [1]
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

The Dixie Fire's advance northward was slowed by the 2012 Reading Fire footprint, but the Dixie Fire ultimately burned 73,240 acres within the park—approximately 69% of the park's total area. 12,845 acres, or 18% of that area, burned at a severity that left the landscape unchanged. 34,450 acres, or 49% of the burned area in the park, burned ...
The state has more than one thousand major reservoirs, of which the largest two hundred have a combined capacity of over 41,000,000 acre-feet (51 km 3). [1] Most large reservoirs in California are located in the central and northern portions of the state, especially along the large and flood-prone rivers of the Central Valley.
California region, with its 10 4-digit subregion hydrologic unit boundaries. The California water resource region is one of 21 major geographic areas, or regions, in the first level of classification used by the United States Geological Survey in the United States hydrologic unit system, which is used to divide and sub-divide the United States into successively smaller hydrologic units.
