DRAINAGE AREA - 1,239 mi² of which 74 mi² probably is noncontributing.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1993 to current year.
GAGE -

Water-stage recorder. Datum of gage is 1,340.00 ft above NGVD of 1929. (discontinued)

Current datum of gage is 1,340.62 ft. above man sea level. (NAVD88) Obtained Nov. 5, 2020 with Trimble R10 set over the wire-weight check bar for 1-hour static survey processed by OPUS.

pH: May 1998 to March 2015 (YSI discontinued).

pH (EXO): Sep. 2014 to current year.

WATER TEMPERATURE: May 1998 to March 2015, March 2017 to July 2019 (YSI discontinued).

WATER TEMPERATURE (EXO): Sep. 2014 to current year.

DISSOLVED OXYGEN (YSI LUMIN): June 2007 to March 2015 (YSI discontinued).

DISSOLVED OXYGEN (EXO): Sep. 2014 to current year.

TURBIDITY (YSI 6026): Oct. 1998 to Dec. 2006 (YSI 6026 discontinued).

TURBIDITY (YSI 6136 sensor): July 2004 to Sep. 2005, December 2006 to March 2015, March 2017 to July 2019 (YSI 6136 discontinued).

TURBIDITY (EXO sensor): Sep. 2014 to current year.

INSTRUMENTATION - Multiparameter water-quality monitor.
REMARKS - Interruptions in record are due to ice conditions or malfunction of the recording instrument or sensors. Instruments used to measure turbidity conform to ISO 7027 standards and were made using Yellow Springs Instrument (YSI) 6026 and 6136 sensors. As of March 2015, turbidity is being measured by an EXO sensor.
