The California Department of Water Resources has created an interactive map that shows geospatially referenced groundwater levels, groundwater table elevation, and subsidence in California. The map includes: Groundwater depth below ground surface; Groundwater elevation; Groundwater change in elevation from year to year

Sep 12, 2024 · Fashioned after the popular California Water Map, this 24×36-inch poster was extensively re-designed in 2017 to better illustrate the value and use of groundwater in California, the main types of aquifers, and the connection between groundwater and surface water.
We found that California’s drinking water supply system relies on approximately 157 million acres of land spanning 8 states to collect, filter, and deliver water. Only 16% of this land is strictly protected from development and degradation (e.g., wilderness areas, national parks).

Groundwater is any water found beneath the Earth’s surface. Despite being difficult to visualize, groundwater makes up a significant portion of the Earth’s water. When rain falls to the ground, the water does not stop moving. Some of it flows along the surface in streams, rivers, and lakes; some of it is used by plants; some evaporates and returns ...
Water in aquifers may be brought to the surface naturally through a spring, or can be discharged into lakes and streams. However, most groundwater is brought to the surface by pumping it through a well (which draws the water like soda through a straw) that is drilled into the aquifer. Wells come in different shapes and sizes, depending on the type ...
While surface water quality varies due to erosion, runoff, pollution, plant matter, animal waste, and other possible contaminants, groundwater quality is generally more stable. That is because an aquifer’s pore spaces act like a coffee filter, trapping sediment and other particles (e.g., the “coffee grounds”, such as bacteria), naturally purifying ...
Groundwater is one of California’s greatest natural resources, making up a significant portion of the state’s water supply, and serving as a buffer against the impacts of drought and climate change. During a typical year, groundwater makes up approximately 40 percent of California’s total water supply, and makes up to 60 percent (or more) during dr...

Environmental water use falls into four categories: water in rivers protected as “wild and scenic” under federal and state laws, water required for maintaining habitat within streams, water that supports wetlands within wildlife preserves, and water needed to maintain water quality for agricultural and urban use.

Jun 10, 2024 · On average, groundwater basins provide approximately 40% of the water used by California’s farms and communities, and significantly more in dry years. Many communities rely entirely on groundwater for drinking water, and it is a critical resource for many Central Valley and coastal farmers.
