National Archive of Marine Seismic Surveys (NAMSS)
The National Archive of Marine Seismic Surveys (NAMSS) is a marine seismic reflection data archive consisting of data acquired by or contributed to U.S. Department of the Interior agencies. The USGS is committed to preserving these data on behalf of the academic community and the nation. Data are provided with free and open access.

NWIS Current Water Data (Real-Time Data)
The USGS provides real-time or near-real-time conditions water data at sites across the Nation. Current data typically are recorded at 15- to 60-minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events.
USGS Mobile Water Data
The USGS Mobile Water Data site highlights USGS current conditions water data in a mobile-friendly website, allowing users to monitor conditions at a favorite river or stream or locate nearby monitoring locations. All USGS current conditions water data is available.
National Water Information System (NWIS) Mapper
The NWIS mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.
Water Quality Portal
The Water Quality Portal integrates and provides access to publicly available water-quality data from databases such as USGS NWIS and BioData, EPA STORET, and USDA-ARS STEWARDS through a single search interface.
National Ground-Water Monitoring Network (NGWMN) Data Portal
The NGWMN Data Portal provides access to groundwater data from multiple, dispersed databases in a web-based mapping application. The Portal contains current and historical data including water levels, water quality, lithology, and well construction.
USGS Sediment Data Portal
Identify, access, and interpret USGS discrete and (or) daily suspended sediment data suspended-sediment and related data. The U.S. Geological Survey National Water Information System (NWIS) is the original source for all suspended-sediment data provided in the portal.
USGS Flood Event Viewer
During large, short-term events, the USGS collects streamflow and additional data (including storm tide, wave height, high-water marks, and additional sensor deployments) to aid in documenting flood events. The USGS Flood Event Viewer provides convenient, map-based access to downloadable event-based data.
StreamStats Application
StreamStats provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more. Available information varies from state to state.
