SURFACE-WATER RECORDS
PERIOD OF RECORD - Jul 8, 2005 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is unknown
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 - SPECIFIC CONDUCTANCE: Dec 2011 to current year. pH: Dec 2011 to Dec 2013. WATER TEMPERATURE: Dec 2011 to current year. DISSOLVED OXYGEN: Dec 2011 to Dec 2013. TURBIDITY: Dec 2011 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: Oct. 9-13, Jan. 13-15, Jun. 3-5, Jun. 7-8, Jul. 5, Aug. 23, rated good; Oct. 14-17, Jul. 6, rated fair; Oct. 18, Feb. 21, Sept. 19-20, rated poor.

WATER TEMPERATURE: For Water Year 2017, record is rated excellent, except for the following periods: Jun. 29 - Jul. 2, rated good; Jul. 3-6, rated fair; Sept. 19-20, rated poor.

TURBIDITY: For Water Year 2017, record is rated excellent, except for the following periods: Oct. 17-18, Jun. 20, 30, rated poor.

As of October 26, 2015, turbidity data collected using YSI EXO2 sensors (previously collected using YSI 6136 6-series sensors). ote 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.
