SURFACE-WATER RECORDS

PERIOD OF RECORD - March 2012 to current year (seasonal stage record only).

GAGE - Water-stage recorder with satellite telemetry. Datum of gage is 1,040.00 ft above National Geodetic Vertical Datum of 1929.

REMARKS - Accuracy of gage height records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, gage height records fair to good, unless otherwise noted. Seasonal Water Year record generally collected from October 1-31 and April 1 to September 30.

EXTREMES FOR PERIOD OF RECORD - Maximum gage height, 21.45 ft, May 8, 2015; minimum gage height, 6.04 ft, September 3, 7-8, 2012.

EXTREMES FOR WATER YEAR 2012 - Maximum gage height, 16.39 ft, April 15, 2012; minimum gage height, 6.04 ft, September 3, 7-8.

EXTREMES FOR WATER YEAR 2013 - Maximum gage height, 18.40 ft, May 30, 2013; minimum gage height, 6.17 ft, October 4, 2012.

EXTREMES FOR WATER YEAR 2014 - Maximum gage height, 18.81 ft, June 4, 2014; minimum gage height, 6.15 ft, March 2, 2014.

EXTREMES FOR WATER YEAR 2015 - Maximum gage height, 21.45 ft, May 8, 2015; minimum gage height, 6.25 ft, March 1, 2015.

WATER-QUALITY RECORDS

PERIOD OF DAILY RECORD - WATER TEMPERATURE: August 2007 to present (seasonal records only). SPECIFIC CONDUCTANCE: August 2007 to present (seasonal records only). TURBIDITY: August 2007 to present (seasonal records only). DISSOLVED OXYGEN: August 2007 to present (seasonal records only).

INSTRUMENTATION - Seasonal deployment of a continuous water-quality monitor. Measured parameters include water temperature, specific conductance, dissolved oxygen, and turbidity. Turbidity measurements conform to ISO 7027 standards.

EXTREMES FOR PERIOD OF RECORD - These extremes may have been exceeded during non-measured periods. WATER TEMPERATURE: Maximum, 32.8°C, July 18, 2011 and July 19, 2012; minimum, 1.1°C, March 26, 2013. SPECIFIC CONDUCTANCE: Maximum, 6,080 uS/cm, October 3, 2013; minimum, 139 uS/cm, August 24, 2016. DISSOLVED OXYGEN: Maximum, 23.4 mg/L, July 3, 2012; minimum, 0.1 mg/L, April 14, 2014. TURBIDITY: Maximum, 2220 FNU, July 12, 2016; minimum, 2.0 FNU, September 16, 2015.
