PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text
Station operated in cooperation with Fairfax County, Virginia

Gage is being relocated. During this transition period, discharge data is only partially available. We are working to get discharge back online as soon as possible. We appreciate your patience during this time.
NOTE: During storm events, backwater effects on stage and discharge determinations at this station are likely. Streamflow data displayed on this page may be significantly different from actual values during these events. Adjustment of data for backwater effects can only be done after detailed analysis. Users are encouraged to contact this office for more information.
This station managed by the Richmond Field Office.
