WATER-QUALITY RECORDS

PERIOD OF RECORD.--December 1987 to current year. For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=09171100

PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: December 1987 to current year.

WATER TEMPERATURE: December 1987 to current year.

INSTRUMENTATION.--Water-quality monitor since December 1987.

REMARKS.--Daily specific conductance record is good except Oct. 6, 7, Nov. 10, 11, Feb. 23, 24, Mar. 18, 24, 25, 29, 30, Apr. 6, 7, 18, 29, May 3, 12, 13, 18-20, 23, June 1, 2, July 28, 29 which are fair and Oct. 8, Nov. 12, Feb. 25, Mar. 31 to Apr. 2, Apr. 8, 9, 19, 20, May 4-6, 24-27, June 3 and Aug. 1-3 which are poor. Daily water temperature record is good. Daily data that are not published are due to probes being isolated by sediment and severe fouling.

EXTREMES FOR PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: Maximum recorded, 57,700 microsiemens/cm, June 22, 1990 (may have been higher June 19-22, 1990 when probe was out of water); minimum recorded, 256 microsiemens/cm, June 23, 1995 (may have been lower during period of missing record Apr. 3-20, 1993).

WATER TEMPERATURE: Maximum, 34.6°C, July 19, 2003; minimum, -1.0°C, Dec. 23, 1995 (temperatures published as 0.0°C may have been lower during water years 1988-95).

EXTREMES FOR CURRENT YEAR.--

SPECIFIC CONDUCTANCE: Maximum, 18,200 microsiemens/cm, Feb. 6; minimum, 423 microsiemens/cm, Apr. 14.

WATER TEMPERATURE: Maximum, 34.6°C, July 19; minimum, -0.3°C, Jan. 2, Feb. 11.
