WATER-QUALITY RECORDS
PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Oct 2009 to current year. pH: Oct 2009 to Dec 2013. WATER TEMPERATURE: Oct 2009 to current year. DISSOLVED OXYGEN: Oct 2009 to current year. TURBIDITY: Oct 2009 to current year.
REMARKS -

Interruptions or periods of missing record may be due to instrument failure, ice conditions, no flow conditions, or data corrections exceeding allowable criteria, which were deleted.

SPECIFIC CONDUCTANCE: For Water Year 2017, record is rated excellent, except for the following periods: May 14-26, rated good.

WATER TEMPERATURE: For Water Year 2017, record is rated excellent, except for the following periods: Aug. 2, 15, rated poor.

DISSOLVED OXYGEN: For Water Year 2017, record is rated excellent, except for the following periods: Jul. 19 - Aug. 18, Sep. 27-30, rated good; Aug. 19-21, rated fair; Aug. 2, 15, rated poor.

TURBIDITY: For Water Year 2017, record is rated excellent, except for the following periods: Aug. 2, rated poor.

As of May 3, 2016, turbidity data collected using YSI EXO2 sensors (previously collected using YSI 6136 6-series sensors). Note that extreme values recorded using YSI EXO2 sensors may exceed those previously recorded using YSI 6136 sensors. Manufacturer specifications of range and accuracy for both sensor models are as follows: YSI 6136: 0 to 1000 FNU, ±2% of the reading or 0.3 NTU (whichever is greater). YSI EXO2: 0 to 999 FNU: 0.3 FNU or ±2% of reading (whichever is greater); 1000 to 4000 FNU: ±5% of reading.
