Click to hide Water-Year Summary instructions and information
  • Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
  • For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
  • For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
  • For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
  • Not all sites have reports available for every water year.

USGS Water-Year Summary 2021
02277110 ST. LUCIE ESTUARY AT A1A (STEELE PT), STUART, FL
LOCATION - Lat 27°11'58", long 80°12'25" referenced to North American Datum of 1927, in NW 1/4 SE 1/4 NE 1/4 sec.02, T.38 S., R.41 E., Martin County, FL, Hydrologic Unit 03090202, middle of Evans Crary Sr. Bridge footing, 2.7 mi west of Atlantic Ocean, 3.4 mi southeast of Stuart.
DRAINAGE AREA - Indeterminate.
REVISIONS HISTORY - WDR-US-2009, site 02277110: maximum gage height, WDR FL-04-2A, WDR FL-05-2A, WDR-US-2006-2008, site 02277110.
The Specific conductance (uS/cm.TOP) and Salinity (ppt.TOP) data, for the period June 15 to August 8, 2017 was revised on March 14, 2018, bad record removed.  The Specific conductance (uS/cm.TOP) and Salinity (ppt.TOP) data, for the period August 8 to October 17, 2017 was revised on March 14, 2018, due to an incorrect start time for a fouling correction, previously provided on nwisweb was revised.  Daily values are available online at http://waterdata.usgs.gov/nwis.
SURFACE-WATER RECORDS
PERIOD OF RECORD - DISCHARGE: August 1997 to September 2000. GAGE HEIGHT: August 1997 to current year.
GAGE - Satellite data collection platform with water-stage shaft encoder. Prior to October 1, 2000, an acoustic Doppler velocity meter. Datum of gage is National Geodetic Vertical Datum (NGVD) of 1929, determined from VERTCON, and 1.45 ft below North American Vertical Datum (NAVD) of 1988. Gage height data prior to water year 2003 are 0.07 ft lower than current datum. This datum was taken into account and the data prior to water year 2003 has been updated.
COOPERATION - South Florida Water Management District.
REMARKS - The station was established as part of a project managed by U. S. Geological Survey in cooperation with South Florida Water Management District. Scientific Investigations Report 2004-5028 Application of Acoustic and Optic Methods for Estimating Suspended-Solids Concentrations in the St. Lucie River Estuary, Florida - Patino, Eduardo; Byrne, Michael J. was published.
EXTREMES FOR PERIOD OF RECORD - DISCHARGE: Maximum positive discharge, 48,900 ft³/s Aug. 31, 1997; minimum negative, 44,600 ft³/s July 24, 2000. GAGE HEIGHT: Maximum gage height, 5.45 ft, Sept. 25, 2004; minimum, -1.28 ft Apr. 28, 1998.
