Streamflow and Rainfall Map
Information About Map
Each oval-shaped label represents a USGS gauge and shows the most current flow reading in cubic feet per second. When flow information is not available, a rectangular-shaped label shows the most current gauge height reading in feet.
The information on the streamflow map is updated every 15 minutes with data obtained from the U.S. Geological Survey (USGS), though not all gauges are updated simultaneously.
Click on a label to get more USGS information along with the National Weather Service forecast.
Click, hold and drag to reposition the map.
