The USGS Flood Event Viewer (FEV) is the public data discovery component of the Short-Term Network (STN) database. Data viewable and downloadable from this page are from the STN database.
This application relies on the STN Web Services to retrieve and display STN data. Application developers and general data seekers are encouraged to use the web services data API to retrieve STN data. Visit the STN Web Services Documentation Page for more information, including full documentation of available endpoints and examples. See the STN Data Dictionary for field names and definitions.
This application integrates with the USGS National Water Information System (NWIS) database for display of time-series water data. As a user of FEV you will encounter links to NWIS pages and data sources, which are maintained separately from STN and FEV.
These data are preliminary or provisional and are subject to revision. They are being provided to meet the need for timely best science. The data have not received final approval by the U.S. Geological Survey (USGS) and are provided on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from the authorized or unauthorized use of the data.
Inundated areas shown should not be used for navigation, regulatory, permitting, or other legal purposes.
