Featured Product: Understanding and Managing the Effects of Groundwater Pumping on Streamflow
It is a common misconception that streamflow depletion stops when groundwater pumping stops. This diagram shows the residual effects of streamflow depletion after pumping stops.
Wells that pump groundwater out of aquifers can reduce the amount of groundwater that flows into rivers and streams, which can have detrimental effects on aquatic ecosystems and the availability of surface water.
Estimation of rates, locations, and timing of streamflow depletion due to groundwater pumping is needed for water-resource managers and users throughout the United States, but the complexity of groundwater and surface-water systems and their interactions presents a major challenge. The understanding of streamflow depletion and evaluation of water-management practices have improved during recent years through the use of computer models that simulate aquifer conditions and the effects of pumping groundwater on streams.

The USGS Active Groundwater Level Network includes about 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months.

USGS Groundwater-Related Publications
USGS Groundwater-Related Software Updates and New Releases
USGS scientists study the hydrogeology of geothermal fields around the United States. The insights gained during these studies can be beneficial for the design of the geothermal drilling program and protection of the overlying aquifer during construction. Our improved understanding of these important natural resources may also be useful for the development of future geothermal fields and other energy-related activities, such as drilling for oil and natural gas in similar fractured-bedrock settings. These field photos are from USGS science activities at two different study sites.
