National Water Monitoring Network
To manage our water resources effectively, we need to understand how much water is available and its usefulness. The USGS monitors the nation’s water resources through various national observing networks that use a range of technologies and methods to assess real-time water conditions and predict future changes in water availability for human and ecological uses.
Assessing River Erosion and Sedimentation in Ecuador
In cooperation with the U.S. Army Corps of Engineers, USGS is helping Ecuadorian government officials from the Electric Corporation of Ecuador (CELEC) develop strategies for managing sediment and erosion in the Río Coca basin after the 2020 collapse of the 144-meter-tall San Rafael waterfall.
Next Generation Water Observing System (NGWOS)
The Next Generation Water Observing System (NGWOS) supports water availability assessments, management, and prediction by enhancing water observations in basins that represent major U.S. hydrologic regions. NGWOS provides high-resolution, real-time data on water quantity, quality, and use, as well as advance the development and application of new sensor technologies and remote sensing methods.
Sediment Laboratories
The USGS maintains sediment laboratories in several Water Science Centers and offices across the country.
Sediment Surrogate Techniques
USGS develops and uses “surrogate” techniques to estimate sediment at times when it can’t be physically measured through samples.
Sediment Sampling and Data Processing
USGS collects sediment samples at thousands of locations across the U.S. using nationally consistent methods.
Sediment Acoustics
The U.S. Geological Survey recognizes the need to provide sediment acoustic training and to develop standardized techniques and practices.

Fluvial Sediment and Geomorphology: Resources for Monitoring and Analysis
The USGS collects fluvial sediment and geomorphic data and conducts related research at numerous sites across the Nation. This information is essential to informed solutions to sediment-related and overall water resource management issues.
Groundwater and Streamflow Information Program
The Groundwater and Streamflow Information Program serves as the national source of impartial, timely, quality-assured, and relevant water data for short- and long-term water decisions by local, State, tribal, regional, and national stakeholders. Our objectives are to collect, manage, and disseminate consistently high-quality and reliable hydrologic information in real-time and over the long-term.
