REMARKS - Accuracy of records is discussed in the annual Station Analysis archived at the USGS MO Water Science Center.  
WATER-QUALITY RECORDS
PERIOD OF DAILY RECORD - WATER TEMPERATURE: Jul 2005 to Jun 2010, Nov 2010 to Sept 2019. SPECIFIC CONDUCTANCE: Jul 2005 to Jun 2010, Nov 2010 to Sept 2019. pH: Jul 2005 to Nov 2008, Oct 2012 to Dec 2013. DISSOLVED OXYGEN: Jul 2005 to Nov 2008, Oct 2012 to Dec 2013. TURBIDITY: Jul 2005 to Nov 2008, Oct 2012 to Sept 2019.
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 2019, record is rated excellent except for the following periods: Mar 10-11, May 9-10, May 25-26, Jun 24-25, Aug 26-28, rated good; Mar 12-13, May 27, Jun 26-27, Aug 29-30, rated fair; Mar 14-19, May 28 - Jun 7, Jun 28, Aug 31 - Sept 4, rated poor.

WATER TEMPERATURE: For Water Year 2019, record is rated excellent except for the following periods: Jun 5-7, Jun 24, rated good; Jun 25, rated fair, Jun 26-28, rated poor.

TURBIDITY: For Water Year 2019, record is rated excellent except for the following periods: Sept 1-4, rated good; May 24 - Jun 2, Jun 21-23, rated fair.

As of August 25, 2015, 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.
