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.

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.

Surface Water-Quality Monitoring Network (WQN)

Pennsylvania’s Statewide Surface Water-Quality Monitoring Network (WQN) currently consists of 124 sites that are sampled between 6 and 20 times a year. Chemical analysis includes nutrient, major ions, and selected metals. Pesticide sampling is conducted twice a year at 5 locations. Biological sampling for benthic macroinvertebrates is conducted annually at 80 sites.

The WQN was...

Water Quality in Lake Pontchartrain and western Mississippi Sound during openings of Bonnet Carré Spillway

The Bonnet Carré Spillway, located about 28 miles northwest of New Orleans, Louisiana, was constructed in the early 1930s as part of an integrated flood-control structure for the lower Mississippi River Plain. The spillway is designed to divert water from the Mississippi River into Lake Pontchartrain, thus relieving pressure on levees downstream. Opening of the spillway occurs when measured...
