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.

USGS Streamgaging Network

The USGS Groundwater and Streamflow Information Program supports the collection and (or) delivery of both streamflow and water-level information for more than 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: 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...

Transboundary Assessments of Water Quality in the Pacific Northwest

In 2019, the USGS began studying the baseline water-quality of selected transboundary rivers in the Pacific Northwest. These studies are designed to characterize current water-quality conditions so as to facilitate future assessments of potential impacts related to upstream mining activities.

Lake Koocanusa Water Quality

Lake Koocanusa is a transboundary reservoir located in southeastern British Columbia and northwestern Montana. The reservoir was officially impounded in 1972 after construction of Libby Dam, which began in 1966. The dam was constructed as part of a treaty between the United States and Canada to cooperatively develop the water resources of the Columbia River drainage basin. The reservoir has a...

Atmospheric Warming, Loss of Snow Cover, and Declining Colorado River Flow

Declining snow cover is playing a key role in decreasing the flow of the Colorado River, “the lifeblood of the Southwest,” by enabling increased evaporation. As the warming continues, increasingly severe water shortages are expected.

National Hydrologic Model Infrastructure

The USGS National Hydrologic Model (NHM) infrastructure supports the efficient construction of local-, regional-, and national-scale hydrologic models. The NHM infrastructure consists of: 1) an underlying geospatial fabric of modeling units with an associated parameter database, 2) a model input data archive, and 3) a repository of the physical model simulation code bases.
