Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown

API stands for Application Programming Interface and provides a developer with programmatic access to a proprietary software application. An API is software that makes it possible for application programs to interact with each other and share data.
PHyLiSS is a generalized coupled hydrologic and hydrogeochemical model of prairie-pothole wetland ecosystems. The current version of PHyLiSS has the capability to simulate wetland hydrology and salinity. Future iterations will be able to simulate the impacts of changing hydrology and salinity on biota.
The USGS presents video and photographs of seafloor segments off California, from the U.S.-Mexico border to the Oregon State line. The USGS collected this imagery as part of the California Seafloor Mapping Program, a large collaborative effort supported by the ...
The StreamStats application uses data web services that were created for it. When in use, the application manages interactions between the user and the services. However, the web services can be directly accessed using the StreamStats Service API documented here or consumed by a custom client application using HTTP protocols.
The USGS Coastal and Marine Geology Program (CMGP) Internet Map Server is an interactive mapping service which allows the user to explore and download GIS data sets published by CMGP.
The water level of Wapato Lake dictates the size (surface area) of the lake and the amount of water that it stores. This web page allows the user to interactively explore Wapato Lake water level data and how the water level translates into lake area and volume.
StreamStats is a Web application that incorporates a Geographic Information System (GIS) to provide users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes.
The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.
An interactive map provides access to estimates of depth-to-water and water-table elevation for the Portland, Oregon, metropolitan area, along with estimates of their relative uncertainty.
StreamStats is a Web-based Geographic Information Systems (GIS) application that provides users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes.
The interactive sea-level rise visualization tool results from a collaborative effort between NOAA's Coastal Services Center, USGS WARC, and USGS Mississippi Water Science Center. The tool illustrates the scale of potential flooding, but not the exact location, and does not account for erosion, subsidence, sediment accretion, or future construction.
WARC's Advanced Applications Team develops and maintains databases and applications to help the Alabama Department of Transportation and the U.S. Fish and Wildlife Service ensure new road construction and existing road maintenance at waterway crossings don't adversely affect threatened and endangered species dependent on those waterways.
