PERIOD OF RECORD - January 09, 2015 to October 19, 2017.

GAGE - Water-stage recorder and data-collection platform. Datum of gage is the North American Vertical Datum of 1988.

WATER-QUALITY RECORDS

PERIOD OF RECORD - Water-quality monitor installed September 4, 2015. Period of record from September 4, 2015 to October 19, 2017. Site discontinued on October 19, 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 current year, water temperature, specific conductance, FDOM and turbidity are published as instantaneous maximum and minimum, and daily mean. October 2016 to current year turbidity 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.
