Our mission is to collect and disseminate reliable, impartial, and timely information that is needed to understand the Nation's water resources.
Endocrine disrupting chemicals (EDC) threaten the reproductive success and long-term survival of sensitive aquatic populations in the U.S. National Park Service (NPS). The project employs a standardized EDC risk assessment framework to link new and ongoing research efforts in individual Parks and in Park Monitoring Networks, in order to provide a service-wide assessment of EDC risk in the NPS.
This web mapping application provides access to many of Grand Canyon Monitoring and Research Center’s most commonly used map layers they use in support of science efforts occurring throughout the Colorado River corridor.
The USGS will operate four water-quality stations in the New Hope arm of Jordan Lake
Water-quality will be monitored:
Biweekly during April through October of each year
April 2012 - October 2013 and April 2017 - October 2018
Water-quality stations for the Jordan Lake study
Real-Time streamflow data for the Lower Roanoke
Map of groundwater monitoring locations in Moore County, NC.
As part of the cooperative groundwater study between the USGS and Moore County, a network of monitoring-well sites with groundwater-level recorders was established at selected available locations in Moore County.
The Atlantic Coastal Plain aquifers and confining units of South Carolina are composed of crystalline carbonate rocks, sand, clay, silt, and gravel and contain large volumes of high-quality groundwater. The aquifers have a long history of use dating back to the earliest days of European settlement in the late 1600s. Although extensive areas of some of the aquifers have or currently (2015).

The FishVis Mapper is the product of an Upper Midwest and Great Lakes LCC project, “A Regional Decision Support Tool for Identifying Vulnerabilities of Riverine Habitat and Fishes to Climate Change” that developed an approach for predicting fish species occurrence under current climate conditions and project how fish species occurrence may change under future climate conditions.
USGS Flood Inundation Maps , along with Internet information regarding current stage from the USGS streamgage, provide emergency management personnel and residents with information that is critical for flood-response activities, such as evacuations and road closures, as well as for post-flood recovery efforts.
All data collected during this project will be available online in the USGS National Water Information System (NWIS).
New York Nowcast predicts water quality conditions at select beach swimming areas in NY. The Nowcast estimates conditions by merging environment and climate data with variables measured at a beach by 8 AM each morning and entering them into a computer program which provides a probability from 1 to 100 as to whether or not the beach has exceeded the bathing-water standard of 235 units of E. coli.
