Realtime Streamflow Data

This webpage will be removed from service on December 31, 2017.

To better serve constituents, GBRA has upgraded its streamflow data map. The new map includes 16 additional gauges. Click here to view the new map.

This page is updated every 15 minutes, on the quarter hour, with data obtained from USGS. Each red dot represents a USGS gauge and the label shows the most current flow reading in cubic feet per second (cfs), or gauge stage in feet, or lake elevation (msl). Move your mouse over a red dot to get more USGS information along with the National Weather Service forecast. Make note of the timestamp associated with the observed values as not all gauges are updated by USGS at the same time. (+/-0.00) - indicates change in 24 hours.
