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.

Data is good, interface not intuitive

I tapped the “+” symbol to add a gauge but none appeared on the map. I had to pinch or pan the map to get the markers/gauges to appear. I’d recommend showing gauges on initial load, or at least show gauges on the map after a 1 second delay.

Data shows current conditions. It would be fantastic if data included average conditions or trends. E.g. I know the Cumberland River is 27ft height right now. How does that compare to this time last year? What is the average height during the year?

Hi Pickle-Lickle,

Thanks for your feedback! A new version is in the works right now, which includes a significant user interface overhaul. Regarding the long-term trends of data, we're only able to retrieve real-time data for the past 120 days, so going back a year isn't as straightforward as you might imagine. I'll certainly consider your feedback, though!

If you'd like access to the beta program for the new version, please email and I'll get you added to it.

Thanks again! Looking forward to getting the new update in your hands soon -- trying to put the finishing touches on it now!

No longer works. Please fix.

It was a great ap when it worked, so I gave three stars even though it no longer works. The update didn’t resolve the problem either. I cannot open- it kicks me out when I try to access the ap.
When it worked it was a great ap for someone living along the water. Really hoping it gets fixed ASAP.

Update: the recent update worked, thank you. Ap is working now. Thank you for the quick fix. 5- stars!

Please send an email to with specifics, and I'll get the issue fixed ASAP. There are only a small number of users being affected by crashes right now, so I need more detail to get to the bottom of the cause.

Also, you can remove the app and re-install it if you want to workaround the issue for now.

Thanks in advance!

New Update

I installed the new update then nothing worked. I contacted the developer who already knew what the problem was and was waiting for his fix approval from Apple. For anyone who may have experienced the same problem as I did just remove the old version then install the new one. Or, wait for the fix to arrive then install that update. It’s a good program to have when the river is rising. Thanks.

Thanks, Wvhome! The fix for your issue was released yesterday, and another update just came out today. Should you have any additional problems, don't hesitate to reach out. Thanks for the kind words; an update of this magnitude has been long overdue. Thanks again, and enjoy!
