Water-use terminology in the series of USGS water-use circulars, first published for the year 1950, has changed over time as illustrated here. Some categories were re-named but retained essentially the same definition, while other changes split existing categories or shifted components of one category to another. See the entries for these terms in the...
This study is in a pilot phase during fiscal years 2017 and 2018. The purpose of the pilot phase is to identify possible technical challenges of using the USGS code GSFLOW for simulating groundwater and surface-water flow in the Colorado Plateau principal aquifer system. During the pilot phase, the project will evaluate GSFLOW in the San Juan River Basin (...
The glacial aquifer system is present in parts of 26 states and is subject to a range of climatic conditions from humid to semi-arid. Groundwater availability in the system may be constrained by climatic conditions, poor water quality, hydrogeology, concerns of conflicts with current groundwater users, or the desire to maintain or restore environmental streamflows.

Formation of arroyos in the late 1800s greatly increased erosion across the southwestern United States. Since the 1930s, however, this erosion has decreased, partly because of bank stabilization by introduced saltcedar. With Isleta Pueblo Indian Nation, the Aquatic Systems Branch developed a new sediment dating method using saltcedar tree rings. We applied the method in a landmark study of...

The glacial aquifer system groundwater availability study is a regional study of the USGS Groundwater Resources Program. These regional studies form the basis for the groundwater assessments within a national Water Census. Groundwater is one of the most important natural resources of the nation. It provides half our drinking water and is essential to the vitality of agriculture and industry,...
In this data visualization, you can see how three major components of the water budget vary across the conterminous US. Precipitation is incoming rain and snow; evapotranspiration is outgoing evaporation from soil and water bodies and transpiration through plants; and runoff is excess water that makes its way to lakes and rivers through streams and spring discharges.
At the National Water Census Data Portal you will find national estimates of water budget components for local watersheds, water withdrawal data for counties, tools to calculate statistics of daily streamflow records, modeled daily streamflow at ungaged stations, and access to records of aquatic biology observations.
The U.S. Geological Survey compiles water-use estimates every five years for each State, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Archived datasets underlying the published "Estimated Use of Water in the United States" reports are available. Data incorporating any revisions can be found on NWISWeb.
