WATER-QUALITY RECORDS

PERIOD OF RECORD.--Water years 1996 to current year.

PERIOD OF DAILY RECORD.-- SPECIFIC CONDUCTANCE: March 2011 to Sept. 2013. pH: March 2011 to Sept. 2013. WATER TEMPERATURE: October 1995 to current year. DISSOLVED OXYGEN: October 1995 to current year. TURBIDITY: March 2011 to Sept. 2013.

INSTRUMENTATION.--Water-quality monitor telemeter from Oct. 1, 1995, set for one hour measurement interval, since Mar. 21 2011, set for 15 minute measurement interval. Automatic (event-driven) pump sampler Mar. 21, 2011 to Sept. 19, 2013. Data for parameter code 63680 (Turbidity) was collected using a probe with the following specifications: turbidity, water, monochrome near infrared LED light, 780-900 nm, detection angle 90 +/- 2.5 degrees, FNU (Formazin Nephelometric Units).

REMARKS.--Interruptions in the water-quality record were due to malfunction of the instrument. Specific conductance records rated excellent except the following periods: Dec. 10-17, Jan. 21 to Feb. 12, Mar. 5-18, 20-23, May 8-16, June 1-11, Sept. 2-10 rated good; Mar. 24-26 rated fair; and Mar. 27 to Apr. 5, Sept. 11-18 rated poor. pH records rated excellent except the following periods: Oct. 11-16, June 13 to July 17, July 27 to Aug. 7, Sept. 1-10 rated good; May 2-16, Aug. 8-14 rated fair; and Sept. 11-18 rated poor. Water temperature records rated excellent. Dissolved oxygen records rated excellent except the following periods: Apr. 6-23, June 20-28 rated good; Apr. 24 to May 1, June 29 to July 9 rated fair; and July 10-17 rated poor. Turbidity records rated poor.

EXTREMES FOR PERIOD OF DAILY RECORD.-- SPECIFIC CONDUCTANCE: Maximum, 440 microsiemens, Jan. 23, 2012; minimum, 115 microsiemens, May 1, 2011. pH: Maximum, 8.7 units, June 12, 13, 2012; minimum, 7.5 units, on several days during summer water year 2011. WATER TEMPERATURE: Maximum, 25.3°C, July 7, 2012; minimum, 0.3°C, Jan. 20, 2009. DISSOLVED OXYGEN: Maximum, 14.8 mg/L, Apr. 13, 14, 20, 21, 2013; minimum, 1.7 mg/L, Sept. 30, Oct. 1, 2008. TURBIDITY: Maximum recorded, 100 FNU, Apr. 13, 20, 21, 24, 25, 2013, but may have been higher during periods of missing record; minimum

recorded, 0.0 FNU, on many days, but may have also occurred during periods of missing record.

EXTREMES FOR CURRENT YEAR.-- SPECIFIC CONDUCTANCE: Maximum, 436 microsiemens, Jan. 29; minimum, 215 microsiemens, May 13, but may have been lower during period of

missing record Apr. 6 to May 1. pH: Maximum, 8.5 units, July 18, Aug. 18; minimum, 7.6 units, on several days during summer period. WATER TEMPERATURE: Maximum, 24.7°C, July 20; minimum, 0.6°C, on several days during winter period. DISSOLVED OXYGEN: Maximum, 14.8 mg/L, Apr. 13, 14, 20, 21; minimum, 5.4 mg/L, July 7. TURBIDITY: Maximum recorded, 100 FNU, Apr. 13, 20, 21, 24, 25, but may have been higher during periods of missing record; minimum recorded, 0.0

FNU, on many days, but may have also occurred during periods of missing record.
