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

PROVISIONAL DATA SUBJECT TO REVISION

This gage is monitored in cooperation with:
Link to the St. Johns River Water Management District.
St. Johns River Water Management District 		Link to the US Army Corps of Engineers
US Army Corps of Engineers.
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.
