Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
Data and Tools
Get current water conditions that are important to you, such as water levels, streamflow, temperatures, and more.
Nationally, USGS surface-water data includes more than 850,000 station years of time-series data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall. The data are collected by automatic recorders and manual field measurements at installations across the Nation.
The Lower Colorado Monitoring Network, located along the All-American Canal in Imperial County, California, is a series of groundwater-level and water-quality wells, as well as streamgages and micro-gravity sites. This interactive map displays the sites and provides links to the most current data.

This mapper provides results from the largest-ever assessment of water quality changes in the Nation's streams and rivers. More than 185 million water-quality records from over 600 Federal, State, Tribal, and local organizations were screened as part of this assessment.

This site serves USGS water data (streamflow, groundwater, water quality, site information, and statistics) via automated means using web services and extensible markup language (XML), as well as other popular media types. Services are invoked with the REST protocol. These services designed for high fault tolerance and very high availability.
This interactive webmap plots water-quality data from domestic and public-supply wells sampled by the USGS for the California Groundwater Ambient Monitoring and Assessment Program (GAMA) Priority Basin Project, and allows users to download datasets.
How do we use water in the U.S.?
We all depend on water every day, ranging from the water from our faucets, to the food we eat, to much of the electricity we use. The U.S. and its territories used nearly 322 billion gallons of water per day in 2015. This would cover the continental U.S. in about two inches of water over the course of a year. The national breakdown of...
National water-use data are reported by source (surface water or groundwater, fresh and saline, and total), and category for the United States as a whole. The water-use data presented here are the current best estimates, and may have been revised from previous publications.
