FloodWatch allows users to monitor rivers and streams throughout the United States. Add USGS gages to your favorites for quick monitoring of current gauge height, precipitation, and flood stage.

By leveraging data from the US Geological Survey and National Weather Service, FloodWatch presents the most recent and historical river heights, precipitation totals, discharge, and flood stage data. Graphs are available to help you visualize the rise and fall of the river, precipitation, and streamflow. Note that only US Geological Survey gauges with real-time data capabilities are surfaced within the application; not all United States gauges are available.

FloodWatch is also geared towards those with interests in or near flood plains. If your home or other interests have been flooded in the past or could be flooded in the future, FloodWatch allows you to easily keep an eye on any potential flooding issues.

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.

Needs to update automatically

Good app but would be nice to have the favorites list update automatically and send out notifications when reaching flood stage.

Great App!

This is one of those apps that is useful (not a novelty), is simple, and does exactly as it says.
I live on a river and have boats in the water year round. Knowing what is happening via this app is great. Yes, before the app (and even now) you can go to the NOAA Hydrologic Prediction Service web site and see all the detail. BUT, you can only see one gauge at a time and of course you need a computer.
The app allows for viewing many gauges all at the same time and then looking at the detail of any one of them by just touching it. Add this to your phone and be out of town and you always know what is happening while you are away.
