The USGS collects flood data and conducts targeted flood science to help Federal, State, and local agencies, decision makers, and the public before, during, and after a flood. Our efforts provide situational awareness, drive predictive models, inform infrastructure design and operation, undergird floodplain mapping, assist flood constituent/load quantification, and facilitate flood impact assessments.
Use this website to discover real-time and historic flood data and scientific investigations, and learn how we collect data while addressing logistical and technical challenges.
USGS Flood Current Conditions and Notifications
The USGS offers multiple products that allow our stakeholders and the public to be notified of high-flow conditions and USGS flood response activities:
- WaterWatch: Access current flood and high-flow conditions (image below), along with other streamflow information
- Regional and Local Flood Alerts: View current and historical alerts of flooding and response activities; subscribe to RSS feeds
- WaterAlert: The WaterAlert service provides notifications to your email or phone for changes in water conditions based on thresholds you choose.
