USGS Water-Year Summary 2018
02232400 ST. JOHNS RIVER NEAR COCOA, FL
LOCATION - Lat 28°22'10", long 80°52'22" referenced to North American Datum of 1927, in SE 1/4 sec.25, T.24 S., R.34 E., Brevard County, FL, Hydrologic Unit 03080101, on the downstream side of bridge on State Highway 520, 0.6 mi upstream from Taylor Creek, 0.7 mi downstream from outlet of Lake Poinsett, 8.8 mi west of Cocoa, and 232 mi upstream from mouth.
DRAINAGE AREA - 1,331 mi².
REVISIONS HISTORY - Water temperature data collected January 3, 2018 through February 14, 2018 were removed from publication on March 27, 2018.  During this period the water quality monitor deployment pipe filled with sediment. Data collected were not representative of actual environmental conditions.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1953 to current year.
GAGE - Water-stage recorder, acoustic velocity meter, and data-collection platform. Datum of gage is at NGVD of 1929 and 1.36 below NAVD of 1988. Prior to Oct. 1, 1959, nonrecording gage at site 3.7 mi east on north shore of Lake Poinsett at datum 5.06 ft higher.
COOPERATION - This gage is monitored in cooperation with the St. Johns River Water Management District and the City of Cocoa.
REMARKS - Records include inflow from Taylor Creek.

PERIOD OF RECORD -

SPECIFIC CONDUCTANCE: August 2000 to September 2002, August 2007 to current year. WATER TEMPERATURE: August 2000 to September 2002, August 2007 to current year.

INSTRUMENTATION - Water-quality monitor and data-collection platform.
REMARKS - Extremes for current year and extremes for period of daily record are based on recorded values and may have been exceeded during periods of no record. August 2000 to September 2002, August 2007 to September 2008; water temperature and specific conductance published as daily mean. October 2008 to September 2014; water temperature, specific conductance and dissolved oxygen published as instantaneous maximum and minimum. October 2014 to current year; water temperature and specific conductance published as instantaneous maximum and minimum, and daily mean.
