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.
New England Groundwater Level Network, 2017 - Web application
Locations of active wells (at least one measurement during the previous year) in the New England groundwater level network at the end of 2017. The dataset contains 104 wells with continuous water-level measurements (15-minute to hourly measurements), 182 wells with discrete water-level measurements (monthly measurements at most locations), and 95 wells with intermittent water-level measurements.
Flood Inundation Mapper - New England
USGS Flood Inundation Mapper Web Application
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.
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.
Phenology Viewer
The Phenology Viewer provides a dynamic online map interface that can be used to view USGS Remote Sensing Phenology and other datasets.
Distribution of Hydraulically Fractured Oil and Gas Wells - 1947 through 2010
Find the number of hydraulically fractured horizontal, vertical, and directional oil and gas wells by drill (spud) year and by 8-digit U.S. Geological Survey hydrologic unit (HUC).
Wildlife Health Information Sharing Partnership – event reporting system (WHISPers)
WHISPers, the Wildlife Health Information Sharing Partnership - event reporting system, is a partner-driven, web-based repository for sharing basic information about historic and ongoing wildlife mortality (death) and/or morbidity (illness) events.
