WATER-QUALITY RECORDS

PERIOD OF RECORD.--November 1979 to current year. For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=09169500

PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: November 1979 to current year.

WATER TEMPERATURE: November 1979 to current year.

INSTRUMENTATION.--Water-quality monitor since November 1979 and water-quality monitor with satellite telemetry since July 1991 to current year.

REMARKS.-- Specific conductance record is good except Oct. 8, Feb. 24, 25, Apr. 1, 2 and Sept. 14 which are fair and May 21-28 and Sept. 15, 16 which are poor. Water temperature record is good except Aug. 28 to Sept. 30 which are poor. Daily data that are not published are due to probes being isolated.

SPECIFIC CONDUCTANCE: Maximum, 10,400 microsiemens/cm Sept. 8, 2002; minimum, 140 microsiemens/cm May 25, 1983.

WATER TEMPERATURE: Maximum, 33.5°C Aug. 7, 1981; minimum, -0.5°C Dec. 3-8, 1982.

EXTREMES FOR CURRENT YEAR.--

SPECIFIC CONDUCTANCE: Maximum, 3,010 microsiemens/cm, June 27; minimum, 240 microsiemens/cm, Sept. 9.

WATER TEMPERATURE: Maximum, 32.1°C, July 18; minimum, -0.3°C, Dec. 19.
