FloodWatch 2.0 has been completely rebuilt for speed and clarity. Track real-time river levels, rainfall, and water temperature in the US.
Whether you live near a river, enjoy kayaking or fishing, or simply want to stay informed about potential flooding, FloodWatch keeps you connected to the latest conditions across the United States.
Powered by data from the US Geological Survey (USGS) and National Weather Service (NWS), FloodWatch helps you monitor rivers and streams with precision and confidence.
Key Features
• Real-Time River Data – Track current river height, discharge, precipitation, and water temperature from thousands of USGS gauges nationwide.
• Historical Trends & Graphs – Visualize how river levels, streamflow, rainfall, and temperature change over time.
• Favorites List – Save your most important gauges for instant access to the latest readings.
• Nationwide Coverage – Explore data for rivers and streams throughout the U.S., including flood-stage information from NWS.
• Flood Awareness – Keep watch on flood-prone areas and monitor rising waters before they become a threat.
• Great for Recreation – Check water conditions before heading out to fish, paddle, or swim.
Only USGS gauges with real-time data capabilities are included, so you’ll always get the most accurate and up-to-date information available.
Whether you’re safeguarding your property, planning your next river trip, or simply fascinated by hydrology, FloodWatch gives you the insight to stay prepared when water levels change.
Works just like it says on the tin. Sent in a feedback request and received a thoughtful and personal response rather than a generic “thanks for your suggestion” reply.
Love the Home Screen widgets

Can you add Lock Screen widgets that are compatible with IOS 16?
Developer Response
Hi Bob,Thanks for your note! Yes, lock screen widgets have been on my mind leading up to the release of iOS 16.I'd love to hear more about what you have in mind for lock screen widgets. Can you be specific about what would be useful for you to see on the lock screen?Please drop a line to feedback-floodwatch@d5gtech.com. Looking forward to your input!
Excellent !!!!'nnnnnnn

One of my favorite apps. Fast accurate info. I'd like to see the favorite screen expanded as I'm monitoring all rivers in six states. They fit but kick me out of the app after viewing which is annoying. Also I'd like push capability and the ability to email the charts created. This app is actually better and more user friendly than the USGS web site. Just keep making it better.Also, is like the capability to automatically surf over to the USGS web page without leaving the app like the app on earthquakes takes you to the website and gives the ability to email the page to others. I literally use this app every day - is tremendous with great potential.
Very intuitive

Is there a way to add alerts to the app if what you are monitoring surpasses a certain height?
