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