GAGE - Water-stage recorder and index-velocity meter. Datum of gage is 0.00 ft NAVD of 1988.
REMARKS - Streamflow at this site is affected significantly by astronomical tides. Daily mean discharge was computed using the Godin low-pass filter to remove tidal effects from instantaneous values. By convention, U.S. Geological Survey has established ebb (seaward) flows as positive flows and flood (landward) flows as negative flows.
