USGS Real-time River Conditions
The links below are for streamflow data provided by the United States Geological Survey (USGS). Some stations for specific locations might be down or non-functional, so check back later if the data is old or not being displayed.
Cubic feet per second (cfs): a rate of flow, in streams and rivers, for example. It is equal to a volume of water one foot high and one foot wide flowing a distance of one foot in one second. One “cfs” is equal to 7.48 gallons of water flowing each second. As an example, if your car’s gas tank is 2 feet by 1 foot by 1 foot (2 cubic feet), then gas flowing at a rate of 1 cubic foot/second would fill the tank in two seconds.
