PERIOD OF RECORD.--November 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=07106000

PERIOD OF DAILY RECORD.--

DISSOLVED OXYGEN: November 1987 to current year.

pH: November 1987 to current year.

SPECIFIC CONDUCTANCE: November 1987 to current year.

WATER TEMPERATURE: November 1987 to current year.

INSTRUMENTATION.--Water-quality monitor with satellite telemetry.

REMARKS.-- Daily dissolved-oxygen records are poor. Daily pH records are fair. Daily specific-conductance records are fair except for Apr. 2, July 31, and Sept. 12, which are poor. Daily water-temperature records are fair except for Apr. 6-11, which are poor. Daily data that are not published are either missing or of unacceptable quality.
