2012 SPARROW Models for the Pacific: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.

2012 SPARROW Models for the Southeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.

2012 SPARROW Models for the Southwest: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.

Texas Water Dashboard

The Texas Water Dashboard presents USGS real-time stream, lake and reservoir, precipitation and groundwater data for more than 850 USGS real-time observation stations in Texas.

2002 SPARROW Model Results for the Midcontinental Region of North America: Total Phosphorus and Total Nitrogen

SPARROW model results of long-term mean-annual total nitrogen and total phosphorus in streams of the Midcontinental Region of North America. The simulated loads represent source inputs similar to 2002 and normalized to long-term average hydrologic conditions for the period from 1970 to through 2012.

Washington State Groundwater Projects

This application includes information about ongoing or completed groundwater studies in Washington. Included are studies from coastal areas, the densely populated Puget Sound, central and eastern Washington, and cross-boundary areas shared with Canada, Oregon, and Idaho.

Water Data Labs

Water Data Labs is an experimental site that exposes tools and technologies in development by the USGS Water Data for the Nation software team. Here, users can explore and test experimental products, services, tools, and visualizations.

Regional Stream Quality Assessment (RSQA)

The Regional Stream Quality Assessment (RSQA), part of the National Water Quality Assessment project, seeks to characterize multiple water-quality factors that are stressors to aquatic life (contaminants, nutrients, sediment, and streamflow alteration) and to develop a better understanding of the relation of these stressors to ecological conditions in streams throughout the region.

Kīlauea 2018 - lower East Rift Zone eruption and summit-collapse events

This geonarrative summarizes Kīlauea’s 2018 events, highlighting the historical context and contributions to science.

Delaware River Dashboard

Created for the Office of the Delaware River Master and supporting the USGS Next Generation Water Observing System Delaware River pilot, the Delaware River Dashboard shows provisional real-time water data collected at USGS observation stations in context with weather-related data from other public sources.

Trails Explorer

The Trails Explorer  is a web application showing the current distribution of aggerated trails.  

Interactive Map: Fauquier County Groundwater Recharge

This application allows users to view, query, select, and export mean, 25th, and 75th percentile groundwater recharge data for Fauquier County, Virginia, USA resulting from a soil-water-balance model developed to estimate the mean annual water budget for the period 1996 through 2015 and the annual water budget for a drought-year in 2001.
