WATER-QUALITY RECORDS

PERIOD OF RECORD - SALINITY: April 2009 to current year. SPECIFIC CONDUCTANCE: April 2009 to current year. WATER TEMPERATURE: April 2009 to current year.

COOPERATION - Miami-Dade County.

INSTRUMENTATION - Water-quality monitor.

REMARKS - Elevation of the salinity and water temperature sensor, at present, is to an arbitrary elevation 0.6 ft depth of the mean low-tide; once, an adequate period of record is collected. Salinity computed from specific conductance, corrected and computed through rating in the NWIS database.
