USGS Water-Year Summary 2023

022908205 NORTH RIVER UPSTREAM OF CUTOFF NEAR FLAMINGO, FL

LOCATION - Lat 25°20'19.22", long 80°54'47.58" referenced to North American Datum of 1983, in T.59 S., R.34 E., Monroe County, FL, Hydrologic Unit 03090202, Harney River Quadrangle, right bank, 0.3 mi northeast of the Cutoff, 13.5 mi northwest of Flamingo.

The IQ up-looking ADVM is located at: 25.33825, -80.91287

DRAINAGE AREA - Indeterminate.

REVISIONS HISTORY - Figures of Discharge and Gage height, in ft NAVD88, for the period of record September 7 to November 8, 2016 has been revised. Correction was added to the record. Daily values are available online at http://waterdata.usgs.gov/nwis.

SURFACE-WATER RECORDS

PERIOD OF RECORD - October 2003 to current year.

GAGE - Satellite data collection platform with pressure transducer and acoustic Doppler velocity meter. Datum of gage is North American Vertical Datum of 1988 (NAVD 88).

REMARKS - Streamflow at this site is affected by astronomical tides. Daily mean discharge was computed using the Godin low-pass filter was used to remove tidal effects from unit values. By convention, the U.S. Geological Survey has established ebb (seaward ) flows as positive flows and flood (landward) flows as negative flows.Discharge and gage height records are available in the files of the U.S. Geological Survey. Discharge and gage height 15 minute data can also be accessed online at http://sofia.usgs.gov/. Daily values are available online at http://waterdata.usgs.gov/nwis.

EXTREMES FOR PERIOD OF RECORD - GAGE HEIGHT: Maximum gage height, 1.70 ft Sept. 29, 2022; minimum, -2.44 ft Mar. 6, 2017.

WATER-QUALITY RECORDS

PERIOD OF RECORD - SALINITY (TOP): March 2001 to March 2010. SALINITY (BOTTOM): March 2001 to December 2014. SPECIFIC CONDUCTANCE (BOTTOM): October 2010 to December 2014. WATER TEMPERATURE (TOP): March 2001 to March 2010. WATER TEMPERATURE (BOTTOM): March 2001 to December 2014.

INSTRUMENTATION - Water-quality monitor.

REMARKS - Prior to October 1, 2010 salinity was computed directly from specific conductance using a conversion within the continuous water quality monitor. From October 1, 2010 to current year, salinity is computed from corrected specific conductance data using a rating in the NWIS database. Bottom water quality monitor located at -4.65 ft NAVD88. 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 are available online at http://waterdata.usgs.gov/nwis. Discrete water quality data are available online at http://nwis.waterdata.usgs.gov/fl/nwis/qw.
