WATER-QUALITY RECORDS

PERIOD OF RECORD.--October 1933 to current year. For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=09095500

PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: December 1935 to current year.

WATER TEMPERATURE: April 1949 to current year.

INSTRUMENTATION.--Water-quality monitor since October 1982.

REMARKS.--Daily record of specific conductance is good, except for the periods Dec. 4-18, Aug. 22 to Sept. 30, which are fair, and Oct. 1-4, Oct. 24 to
Dec. 1, Apr. 11-23, May 7-19, which are poor. Daily record of water temperature is good. Missing daily data were due to sensor fouling or instrument malfunctions. Prior to water year 1995, daily maximum and minimum specific conductance data are available in district office.

EXTREMES FOR PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: Maximum, 1,970 microsiemens/cm Jan. 19, 1940; minimum, 190 microsiemens/cm June 17-18, 1993.

WATER TEMPERATURE: Maximum, 28.5°C July 22, 1989; minimum, 0.0°C on many days during winter months.

EXTREMES FOR CURRENT YEAR.--

SPECIFIC CONDUCTANCE: Maximum, 1,650 microsiemens/cm, Feb. 10; minimum, 222 microsiemens/cm, June 2.

WATER TEMPERATURE: Maximum, 26.2°C, July 26; minimum, 0.0°C, on many days.
