USGS Water Information Resources

The U.S. Geological Survey (USGS) Water Resources Discipline, investigates the occurrence, quantity, quality, distribution, and movement of surface and underground waters and disseminates the data to the public, State and local governments, public and private utilities, and other Federal agencies involved with managing water resources. The links below allow you to further investigate water.

USGS Water Information

Water Resources of the United States
Water is one of seven science mission areas of the U.S. Geological Survey (USGS). Science includes streams, lakes, reservoirs, groundwater, aquifers, wells, water quality, and water use.
Water Use in the United States
The U.S. Geological Survey's National Water-Use Information program is responsible for compiling and disseminating the nation's water-use data. The USGS works in cooperation with local, State, and Federal environmental agencies to collect water-use information.
USGS Water Resources Programs
The USGS manages water information at offices located throughout the United States. Although all offices are tied together through a nationwide computer network, each collects data and conducts studies in a particular area.

Other California Water Information

California Department of Water Resources
The Department of Water Resources (DWR) is responsible for managing and protecting California's water resources. DWR works with other agencies to benefit the State's people and to protect, restore and enhance the natural and human environments.

The California Water Plan

California Natural Resources Agency
The agency's mission is to restore, protect and manage the state's natural, historical and cultural resources for current and future generations using creative approaches and solutions based on science, collaboration and respect for all the communities and interests involved.
U.S. Bureau of Reclamation, Mid-Pacific Region
The Mid-Pacific Region, one of five Reclamation regions, covers the northern two-thirds of California, most of western Nevada and part of southern Oregon. The region fulfills water obligations for agriculture, power generation, water conservation, water recycling and reuse while protecting of natural and federally protected cultural resources.
U.S. Fish and Wildlife Service, California Offices
The U.S. Fish and Wildlife Service works with others to conserve, protect and enhance fish, wildlife and plants and their habitats for the continuing benefit of the American people.
