USGS 02236125 ST. JOHNS RIVER AT ASTOR, FL

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

This gage is monitored in cooperation with the St. Johns River Water Management District.

Link to the St. Johns River Water Management District.

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.
