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!

Finally a simple interface with realtime data!


This app is awesome! It has a simple interface that makes it easy to locate stations and get data. The summary page is a nice snapshot and the graphs are great with cfs and feet gauge readings for your viewing preference. This was instrumental in watching local creek levels for paddling my kayak in whitewater.
