Integrated Water Science (IWS) Basins
The U.S. Geological Survey is integrating its water science programs to better address the Nation’s greatest water resource challenges. At the heart of this effort are plans to intensively study at least 10 Integrated Water Science (IWS) basins — medium-sized watersheds (10,000-20,000 square miles) and underlying aquifers — over the next decade. The IWS basins will represent a wide range of...
USGS Next Generation Water Observing System (NGWOS)
Substantial advances in water science, together with emerging breakthroughs in technical and computational capabilities, have led the USGS to develop a Next Generation Water Observing System (NGWOS). The USGS NGWOS will provide real-time data on water quantity and quality in more affordable and rapid ways than previously possible, and in more locations.
Integrated Water Availability Assessments (IWAAs)
The USGS Integrated Water Availability Assessments (IWAAs) are a multi-extent, stakeholder driven, near real-time census and prediction of water availability for both human and ecological uses at regional and national extents.
USGS Streamgaging Network
The USGS Groundwater and Streamflow Information Program supports the collection and (or) delivery of both streamflow and water-level information at approximately 8,500 sites and water-level information alone for more than 1,700 additional sites. The data are served online—most in near realtime—to meet many diverse needs.
Next Generation Water Observing System: Illinois River Basin
The Next Generation Water Observing System provides high-fidelity, real-time data on water quantity, quality, and use to support modern water prediction and decision-support systems that are necessary for informing water operations on a daily basis and decision-making during water emergencies. The Illinois River Basin provides an opportunity to implement the NGWOS in a system challenged by an...
Next Generation Water Observing System: Upper Colorado River Basin
The Next Generation Water Observing System provides high-fidelity, real-time data on water quantity, quality, and use to support modern water prediction and decision-support systems that are necessary for informing water operations on a daily basis and decision-making during water emergencies. The headwaters of the Colorado and Gunnison River Basin provide an opportunity to implement the NGWOS...
Next Generation Water Observing System: Delaware River Basin
The USGS Next Generation Water Observing System will provide high-fidelity, real-time data on water quantity and quality necessary to support modern water prediction and decision support systems for water emergencies and daily water operations. The Delaware River Basin pilot provides an opportunity to develop the NextGen observing system in a nationally important, complex interstate river...
Principal Aquifers of the United States
This website compiles USGS resources and data related to principal aquifers including Aquifer Basics, principal aquifers maps and GIS data, and the National Aquifer Code Reference List.
Flood Frequency Reports
Flood-frequency analysis provides information about the magnitude and frequency of floods based on records of annual maximum instantaneous peak discharges. Accurate flood-frequency estimates, created using consistent and uniformly applied methods, are a key component of any effective flood risk and management program. This is a list of current USGS flood frequency reports published by state...
National Atmospheric Deposition Program (NADP)
The National Atmospheric Deposition Program (NADP) is a multi-partner atmospheric monitoring program that measures the concentrations and deposition of atmospheric constituents across North America. The USGS has been an NADP partner agency since 1981 and participates by providing funds for 82 National Trend Network (NTN) sites.
Powder River: Data for Cross-Channel Profiles at 22 Sites in Southeastern Montana, 1975 through 2019
Powder River rises in the Bighorn Mountains of Wyoming and flows northward through a semi-arid landscape in Wyoming and Montana to the Yellowstone River. The river drains an area of 34,700 square kilometers and has an average discharge of about 500 million cubic meters per year. Cross-channel profile data were collected at 22 sites on the river and its tributaries from 1975 through 2014.
USGS Blue Carbon Projects
Together with partner organizations, the USGS is involved in data collection, analysis, and synthesis to improve estimates of coastal wetland carbon fluxes. This research will help improve science and data availability across a wide range of topics.
