NWDTW 2026

Since 2021, the USGS Real-time Flood Impact Map has evolved through the Next Generation Water Observing System (NGWOS) into an increasingly operational capability that delivers actionable flood impact intelligence.

This hands-on workshop will train participants to enter and document flood impacts within the system. Attendees are encouraged to bring their own flood impact scenarios; alternatively, examples may be selected from National Weather Service flood impact statements. These scenarios will be used for guided, step-by-step instruction on data entry, standards, and quality assurance.

The session will include: (1) an overview of the Real-time Flood Impact Map, (2) criteria for defining and selecting flood impacts, (3) hands-on data entry exercises, and (4) best practices for ensuring consistency and accuracy. The map currently includes more than 6,000 documented flood impacts nationwide and continues to expand in operational use.

Participants will leave prepared to independently contribute high-quality flood impact data and support broader adoption across cooperators and stakeholders.
