Watch Duty: Flood Tracking
Watch Duty App Expands to Monitor Dangerous Floods as Peak Season Arrives
Watch Duty, the free app used by more than 20 million people to track wildfires, has expanded to cover dangerous floods — just as the U.S. enters peak flash flood season WSLS. The move comes one year after catastrophic floods in Texas killed more than 130 people, with many victims never receiving a warning Associated Press.
The app now lets users track flood warnings, see river gauge levels, and get alerts about potential dam or levee failures — all in one place. CEO John Mills called the situation "painful," saying the U.S. is "not spreading enough information fast enough on as many channels as humanly possible" Associated Press.
Texas Floods Exposed a Deadly Information Gap
In July 2025, the Guadalupe River in Texas rose 26 feet in just 45 minutes after remnants of Tropical Storm Barry swept through the Hill Country Associated Press. More than 130 people died. Kerr County was hit hardest. A public outcry followed when it became clear that many victims had never received a flash flood warning.
That disaster exposed the same flaw Watch Duty was built to fix: slow, fragmented official alerts. Mills testified before a U.S. House subcommittee in February 2026 that government alert systems are "crippled by a fragmented bureaucracy" News4Jax. The flood expansion is Watch Duty's direct answer to that failure.
How the App Turns Raw Data Into Plain-Language Alerts
Watch Duty launched its flood feature on June 8, 2026 Click Orlando. About 300 volunteer reporters now sort through radio scanners, satellite images, cameras, and public announcements. They translate complex data from the National Weather Service and the U.S. Geological Survey into simple, plain-language updates.
Watch Duty meteorologist Pete Curran summed up the goal simply: "You're not going to have to go to multiple other entities... It's in one place" Your Valley. Users can now see flood warnings, river levels, and dam failure risks — the same way they already track wildfires and evacuation orders.
From Sonoma County Startup to a 20-Million-User Nonprofit
Mills launched Watch Duty in Sonoma County, California, in August 2021 after a wildfire hit his area with zero official evacuation notices Click on Detroit. The app grew fast. When the Eaton and Palisades fires killed 31 people in Los Angeles in January 2025, Watch Duty added 600,000 users in a single day and became the most-downloaded app in the U.S. — beating ChatGPT and TikTok.
Today the nonprofit runs on a $13.3 million annual budget, funded by grants and more than 65,500 paying members at $25 a year. In April 2026, Google.org gave the app a $2 million grant to strengthen its systems during high-traffic emergencies WSLS. The app operates with 48 full-time staff and roughly 300 volunteers.
Officials Urge Caution Even as Tech Community Backs the App
Not everyone is fully on board. Agencies like Cal Fire have warned that Watch Duty is not an "official source" and that people should rely on government channels first Click on Detroit. Some officials worry that third-party apps can cause confusion or alert fatigue if they fall out of sync with emergency command centers.
But public trust in the app keeps growing. Malibu Fire Brigade Captain David Hertz described Watch Duty as "a democratization of data that empowers people" Your Valley. Resident Matt Blea said the app pushed him to leave his home early during the Eaton Fire — before the house was destroyed. Mills frames the app's rise not as a tech success story, but as proof that government has failed to protect people during disasters.
