  • Additional information:
  • The Virginia Water Science Center has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible.

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.
