SPARROW Mappers
SPARROW mappers are interactive tools that allow the user to explore river streamflow and nutrient and sediment loads and yields and the importance of different sources of contaminants in a particular river basin. Data can be visualized using maps and interactive graphs and tables, and rankings can be shown by state, major watershed, hydrologic unit (HUC), and catchment.
New Water-Quality Directions
As the USGS Water Resources Mission Area looks to the future, we are updating our water programs to meet 21st century water-resource challenges. As part of these updates, we are integrating the National Water Quality Assessment Project's water-resource monitoring, assessment, trends, modeling, and forecasting activities into new WMA programs.
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...
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.
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...
Integrated Water Availability Assessments (IWAAs)
The USGS Integrated Water Availability Assessments (IWAAs) are a multi-extent, stakeholder driven, near real-time census and seasonal 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 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.
Integrated Water Availability Assessments using Cooperative Matching Funds
A group of new projects from across the U.S. will help to support development of National and Regional Integrated Water Availability Assessments (IWAAs). They will be conducted with State and local partners with the support of Cooperative Matching Funds and will focus on improving the data, tools, and information stakeholders need to make water-resource management decisions.
Harmful Algal Bloom (HAB) Cooperative Matching Funds Projects
New projects from coast to coast will advance the research on harmful algal blooms (HABs) in lakes, reservoirs and rivers. The vivid emerald-colored algal blooms are caused by cyanobacteria, which can produce cyanotoxins that threaten human health and aquatic ecosystems and can cause major economic damage.
Urban Waters Federal Partnership Cooperative Matching Funds Projects
The Urban Waters Federal Partnership (UWFP) reconnects urban communities—particularly those that are overburdened or economically distressed—with their waterways by improving coordination among federal agencies.
National Water Quality Laboratory (NWQL)
Offering a wide-range of environemental analytical services, the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL) is a world-class environmental analysis and research laboratory located on the campus of the Denver Federal Center in Lakewood, Colorado.
USGS Rapid Deployment Gages (RDGs)
USGS Rapid Deployment Gages (RDGs) are fully-functional streamgages designed to be deployed quickly and temporarily to measure and transmit stream stage data in emergency situations.
