Water levels and other paddling information at your fingertips! includes information on over 12,000 destinations in the US and Canada. provides water levels, water temperature, and other information, using data collected from over 12,000 gauges.

River flow levels are currently sourced from USGS (United States Geological Survey), NWS (National Weather Service), and the Meterological Service of Canada. Additional sources for gauges are planned for the future.

This might be the best whitewater river app

This app is specifically written for whitewater rivers. It includes a map with a pin for every river gage in US and Canada. Whatever you want in a whitewater river app, it probably already exists in this app. And there is a link for each river for you to submit suggestions to the developer.

WOR Actual ,

This app is exactly what white water paddlers have been looking for. Fantastic compilation of data sources. Carefully built, beautifully displayed. A keeper.

Having fun now! ,

Amazing resource for paddlers! It has everything you would want and things you did not think of - River levels, gauges, gps coordinates, directions and maps to put in and take out, searches of your favorites you can share with friends. Very intuitive and user friendly. This will be so helpful as I branch out to new rivers in my area and across the country.
