  • Due to a lapse in government funding, the majority of USGS websites will not be updated except to provide important public safety information. Websites displaying real-time water data will be updated with limited support. For more information please see www.doi.gov/shutdown.
  • Explore the NEW USGS National Water Dashboard interactive map to access real-time water data from over 13,500 stations nationwide.

USGS 02244040 ST. JOHNS R AT BUFFALO BLUFF NEAR SATSUMA, FL

PROVISIONAL DATA SUBJECT TO REVISION

Data are tidally affected -- Astronomical tides cause significant cycles of approximately 24.84 hours at this site. Because a different portion of the 24.84-hour tidal cycle is averaged in successive daily (24-hour) computations, a systematic secondary oscillation, unrelated to basin hydrology and having a period of about two weeks may be apparent in daily data.

REMARKS.--Computed discharge at this station may differ from individual measurements because of changes in tidal influence, wind, or other factors.
