Realtime Streamflow Data

To better serve constituents, GBRA is upgrading its streamflow data map and seeks your feedback. Please click here to view the new page and share your comments.

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.
