Programs L2 Landing Page
The Groundwater and Streamflow Information Program (GWSIP) is one of four Water Investigations Programs funded by Congress to identify, measure, and assess the Nation’s water resources. The GWSIP is the principal USGS Program for monitoring groundwater and streamflow, including floods and droughts, related to groundwater resources at the regional/national scales.

USGS Flood Experts Respond to High Water in Central, Northeastern U.S.
Crews from the U.S. Geological Survey have been in the field for weeks measuring flooding in the Midwest and in the Mississippi River watershed, and more recently flooding and storm tides on the Northern Atlantic coast, as higher temperatures, heavy rain, snowmelt and nor’easters affected numerous states.
Alaska Earthquake Rattles Florida’s Groundwater Plumbing
At 12:32 am Alaska time on January 23, 2018, a magnitude 7.9 earthquake shook Alaska residents out of their beds and set off fears of a tsunami all down the West Coast. Fortunately, the tsunami was only a few inches in height, but within an hour of the earthquake in Alaska, waves of a different sort were hitting far away in Florida.
Wood River Valley Aquatic Biology and Habitat Assessment
Blaine County’s population nearly quadrupled from about 5,700 to 22,000 people between 1970 and 2010. Residents and resource managers of the Wood River Valley of south-central Idaho are concerned about the potential effects that population growth and the expected increased demand for water might have on the quantity and quality of the valley’s ground and surface waters. Increased water use has...
Groundwater, Aquifers, and Wells
Science to discover and describe the location, condition, and behavior of water in the ground.
Regional Groundwater Studies
These assessments will document the effects of human activities on water levels, groundwater storage, and discharge to streams and other surface-water bodies; explore climate variability impacts on the regional water budget; and evaluate the adequacy of data networks to assess impacts at a regional scale.
Stable Streamgaging Network
At the core of NSIP will be a set of USGS-funded streamgages strategically positioned across the country that are continuously operated to fulfill five Federal needs for streamflow information. These will be a permanent set of core streamgages from which streamflow information would be delivered in real time, uncompromised by changing support from funding partners.
Groundwater Level Data
Measurements of groundwater levels from wells are used to monitor changes in groundwater conditions due to climate variability and withdrawals (pumping). The GWRP has supported the development of a Groundwater Climate-Response Network, a network of wells selected to illustrate the response of the groundwater system to climate variations nationwide.
Geophysical Methods & Applications
USGS conducts research into new and emerging geophysical methods and applications for groundwater investigations. Near-surface geophysical techniques can be used to rapidly and effectively characterize the shallow subsurface and to monitor hydrologic and remediation processes in ways not previously possible with standard technology.

USGS Hurricane Preparedness
Before a hurricane, USGS Scientists undertake a data collection effort of a grand scale. They install a temporary mobile network of sensors along the coasts to collect additional data on the intensity of storm surge, one of the most dangerous elements of a hurricane. This effort provides critical information that allows various USGS partners and emergency responders to make better informed...

Reach-Scale Monitoring | Advances in Stream Gaging
The Arizona Water Science Center demonstrates new methods in Reach-Scale Monitoring to improve accuracy and measurability of high flow events. By installing pressure transducers and using LiDAR to measure topography data, hydrologists are able to simulate flows with two dimensional models which will help better calibrate stream gages. These advances have potential to aid in gathering important...
