States, the District of Columbia, and Puerto Rico. Online access to this data
is organized around these categories:

The USGS 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 our water resources.
