Water-Year Summary for Site 02198810
Streamflow at this site is affected significantly by astronomical tides. By convention, the U.S. Geological Survey has established ebb (seaward) flows as positive flows and flood (landward) flows as negative flows. Unfiltered 15-minute stage, velocity, and discharge data are available upon request.
SPECIFIC CONDUCTANCE: October 1986 to September 1987, April 1988 to November 1989, December 2009 to current year.
pH: November 2013 to current year.
WATER TEMPERATURE: December 2009 to current year.
SALINITY: October 2013 to current year.
CHLORIDE: January 2014 to current year.
For period 10/01/1986 to 09/30/1987: Specific Conductance rated good.
For period 04/01/1988 to 11/30/1989: Specific Conductance rated good.
For period 12/01/2009 to 09/13/2013: Specific Conductance and Water Temperature rated good.
For period 10/01/2013 to 09/30/2014: Specific Conductance and Water Temperature are rated good; pH is rated fair. Computed Salinity is rated good for days for which it is computed. Computed Salinity is missing on many days due to input specific conductance values exceeding the limit of the rating.
For period 10/01/2014 to 09/30/2015: Specific Conductance and Water Temperature are rated good; pH is rated fair. Computed Salinity is rated good for days for which it is computed. Computed Salinity is missing on many days due to input specific conductance values exceeding the limit of the rating.
For period 10/01/2015 to 09/30/2016: Specific Conductance and Water Temperature are rated good; pH is rated good, except for the period 10/22-11/08/2015, which is rated poor. Computed Salinity records are rated good for days in which values could be computed; most of the year is missing due to input specific conductance values being less than the low end of the salinity rating.
For period 10/01/2016 to 09/30/2017: Specific Conductance, Water Temperature, and pH are rated good. Computed Salinity is rated good for days for which it is computed. Computed Salinity is missing on many days due to input specific conductance values exceeding the limit of the rating.
For period 10/01/2017 to 11/22/2017: Specific Conductance, Water Temperature, and pH are rated good. Computed Salinity is rated good for days for which it is computed. Computed Salinity is missing on many days due to input specific conductance values exceeding the limit of the rating.
