This gage is monitored in cooperation with 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.

LOCATION.--Lat 29°35'46", long 81°41'00", referenced to North American Datum of 1927, in SE 1/4 sec.27, T.10 S., R.26 E., Putnam County, FL, Hydrologic Unit 03080103, near left bank, 400 ft upstream from CSX Transportation bridge, 2.4 mi downstream from Cross-Florida Barge Canal, 3.2 mi northwest of Satsuma, and 89 mi upstream from mouth.

DRAINAGE AREA.--6,580 mi2, approximately. Includes Paynes Prairie, a diked sinkhole area of about 650 mi2, which is noncontributing.

PERIOD OF RECORD.--September 1943 to July 1948 (gage heights only), October 1992 to September 2010, October 2010 to current year (filtered).

GAGE.--Water-stage recorder, acoustic velocity meter, water-quality monitor, and data-collection platform. Datum of gage is 10.00 ft below NGVD of 1929 and 10.93 ft below NAVD of 1988. Prior to Oct. 1, 1996 at datum 1.00 ft lower.

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