USGS-DOE Cooperative Studies and Groundwater Monitoring in Nevada
The USGS-DOE Cooperative Studies and Groundwater Monitoring in Nevada website provides an interactive and easy-to-use interface to access groundwater levels, groundwater withdrawal, and water-temperature data for wells on and adjacent to the NNSS.
Groundwater Levels In and Near the Duwamish River Valley, Washington
This web page displays groundwater-level data for selected wells monitored by the U.S. Geological Survey (USGS) in and near the Duwamish River valley, King County, Washington. These data are part of a project to better understand the geology and groundwater in and near the Duwamish River valley and how groundwater may contribute to flooding in the valley.

How does your state use Landsat satellite data? Find out here! For each state, you can download a satellite image, put together an online puzzle, or read a USGS Fact Sheet that contains information about the benefits of Landsat.
York County Water Quality Dashboard
Since 2019, the USGS Pennsylvania Water Science Center has been cooperating with York County, Pennsylvania to implement in-stream monitoring and water-quality sampling to compute, in real time, the concentration, loads, and yields of total nitrogen, total phosphorus, and suspended sediment for 6 major watersheds in the County.
Walker Basin Hydro Mapper
The Walker Basin Hydro Mapper web application provides a basin-wide view of real-time streamflow and reservoir storage capacity for the Walker River Basin in Nevada and California.
Invasive Carp Open Data Hub
The Invasive Carp Open Data Hub is a platform for exploring and accessing USGS data, tools, applications, and publications related to invasive carp research and management.
U.S. Landslide Inventory and Susceptibility Map
A web-based interactive map that combines the national landslide inventory compilation with the national landslide susceptibility map. This searchable map integrates contributions from various local, state, and federal agencies and offers links to the original digital inventory files for more detailed information.
Pennsylvania's Long-Term Surface-Water Quality Network
USGS, in cooperation with the Pennsylvania Department of Environmental Protection (PaDEP), has released a geonarrative detailing the sampling of a network of surface water sites across Pennsylvania.
National Water Availability Assessment Data Companion
The National Water Availability Assessment Data Companion (NWDC) delivers model-based estimates of water supply and demand.
Runoff Estimates for California
Streams, rivers, lakes and reservoirs are important natural resources for irrigation, public supply, wetlands and wildlife. Excess precipitation that flows into these sources is called runoff, and it's an important drought indicator. The California Water Science Center tracks both monthly and annual runoff.
EROS Registration System
The USGS Earth Resources Observation and Science (EROS) Registration System (ERS) consolidates user profile information and authentication for EROS based web services.
