Real-time river and stream conditions at a USGS stream gauge — current streamflo
Real-time river and stream conditions at a USGS stream gauge — current streamflow/discharge (cubic feet per second) and gauge height/water level/stage (feet), i.e. how much water is flowing and how high it is right now. Data is provisional and subject to revision. Requires a USGS site number (e.g. 09380000 = Colorado River at Lees Ferry, AZ).
