USGS Water-Year Summary 2023

251433080265000 WEST HIGHWAY CREEK NEAR HOMESTEAD, FL

LOCATION - Lat 25°14'31.59", long 80°26'51.26" referenced to North American Datum of 1983, in T.60 S., R.39 E., Miami-Dade County, FL, Hydrologic Unit 03090202, located approximately 150 ft upstream of the mouth on the right bank, approximately 6 mi northwest of Key Largo.

DRAINAGE AREA - Indeterminate.

REVISIONS HISTORY - Figures of Discharge and Gage height, in ft NAVD88, for the period of record December 5, 2016 has been revised. Missing record was back-filled. Daily values are available online at http://waterdata.usgs.gov/nwis.

SURFACE-WATER RECORDS

PERIOD OF RECORD - February 1996 to current year.

GAGE - Satellite data collection platform with water-stage shaft encoder and acoustic Doppler velocity meter. Datum of gage North American Vertical Datum of 1988 (NAVD 88).

REMARKS - Daily mean discharge is not published. The discharge for this station is more affected by wind than astronomical tides. Discharge at wind-driven sites may require a different filter (subtidal) than the Godin low-pass filter. Mean monthly discharge tables for the period of record are published. Mean monthly discharge tables only include months with no missing daily mean discharges. Discharge and gage height records are available in the files of the U.S. Geological Survey. Discharge and gage height 15 minute data and mean monthly discharge data can also be accessed online at http://sofia.usgs.gov/. Daily values of gage height are available online at http://waterdata.usgs.gov/nwis. Monthly mean discharge tables are published and are available upon request.

EXTREMES FOR PERIOD OF RECORD - DISCHARGE: Maximum positive discharge, 826 ft³/s Aug. 6, 2007; maximum negative, 1,160 ft³/s Oct. 24, 2005. GAGE HEIGHT: Maximum gage height, 2.59 ft Oct. 24, 2005; minimum, -1.64 ft Mar. 30, 1996.

CLIMATOLOGICAL RECORDS

PERIOD OF RECORD - October 2004 to September 2011. Discontinued.

INSTRUMENTATION - Unshielded standard 8 in. diameter tipping bucket precipitation gage with 0.01 in. resolution.

EXTREMES FOR PERIOD OF RECORD - Maximum daily precipitation, 9.33 in., Sept. 29, 2010.

REMARKS - Precipitation records are available in files of the U.S. Geological Survey. Daily precipitation data is available online at http://waterdata.usgs.gov/nwis.

WATER-QUALITY RECORDS

PERIOD OF RECORD - SALINITY (TOP): February 1996 to current year, SALINITY (BOTTOM): February 1996 to August 2017. SPECIFIC CONDUCTANCE (TOP):October 2010 to current year, SPECIFIC CONDUCTANCE (BOTTOM): October 2010 to August 2017. WATER TEMPERATURE (TOP):February 1996 to current year, WATER TEMPERATURE (BOTTOM): February 1996 to August 2017.

INSTRUMENTATION - Water-quality monitor with top and bottom sensors.

REMARKS - Prior to September 2010 salinity computed directly from specific conductance using a conversion within the water quality monitor. September 16, 2010 to current year, salinity computed from corrected specific conductance data using a rating in the NWIS database. Salinity and water temperature sensors located at -1.99 ft NAVD 88 (TOP) and -3.75 ft NAVD 88 (BOTTOM). Salinity and water temperature records are available in files of the U.S. Geological Survey. Salinity and water temperature 15 minute data can also be accessed online at http://sofia.usgs.gov/. Daily values of salinity and water temperature are available online at http://waterdata.usgs.gov/nwis. Discrete water quality data are available online at http://nwis.waterdata.usgs.gov/fl/nwis.

EXTREMES FOR PERIOD OF RECORD - SALINITY (TOP): Maximum recorded, 50.1 ppt Aug. 14, 15, 2015; minimum recorded, 0.2 ppt occurred on many days during the months of July to Oct. during the 1996, 1997, 1999, and 2001 water years. SALINITY (BOTTOM): Maximum recorded, 49.1 ppt Aug. 14, 15, 2015; minimum recorded, 0.2 ppt occurred on many days during the months of July to Oct. during the 1996, 1997, 1999, and 2001 water years.
