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 ...
Aquifers of the United States Withdrawal rates from the Ogallala Aquifer.. This is a list of some aquifers in the United States.. Map of major US aquifers by rock type. An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to groundwater wells and springs.
The published maps contain base and cultural features not included in these data. This is a replacement for the July 1998 map layer called Principal Aquifers of the 48 Conterminous United States. Purpose: These data are intended for use in publications, at a scale of 1:2,500,000 or smaller.

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 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'
A map showing the contiguous United States and (in insets at the lower left) the two states that are not contiguous Map highlighting Alaska and Hawaii's geographical relationship to the contiguous United States. Alaska in red is in the upper part of the map, while Hawaii is the islands also in red to the far left.
California's groundwater levels rose significantly in 2023, one of the wettest years in decades. State officials say efforts to replenish aquifers helped.
