WATER-QUALITY RECORDS

PERIOD OF RECORD -

Water-quality monitor measuring temperature, specific conductivity and FDOM installed September 25, 2015. Period of record from September 25, 2015 to October 17, 2017. Site discontinued on October 17, 2017.

Turbidity sensor installed on monitor on October 5, 2016. Period of record from October 5, 2016 to October 17, 2017. Site discontinued on October 17, 2017.

INSTRUMENTATION - YSI EXO2 water-quality monitor consisting of temperature, specific conductivity, FDOM and turbidity.

REMARKS - Extremes for current year and extremes for period of daily record are based on recorded values and may have been exceeded during periods of no record. September 2015 to October 2017, water temperature, specific conductance, and FDOM are published as instantaneous maximum and minimum, and daily mean. FDOM readings from this sensor have not been adjusted for potential interferences from turbidity and other constituents.
