09260050 YAMPA RIVER AT DEERLODGE PARK, CO-Continued

WATER-QUALITY RECORDS

PERIOD OF RECORD.--November 1977 to September 1981 published as "09260025, below Little Snake River." April 1982 to September 1983, October 1993 to September 1994, October 1996 to current year. For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=09260050

PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: November 1977 to September 1982.

WATER TEMPERATURE: October 1979 to September 1982, April 2002 to current year.

INSTRUMENTATION.--Water-quality monitor, November 1977 to September 1982. Water-temperature sensor with satellite telemetry since April 2002.

REMARKS.--Daily record of water temperature is excellent. Interruptions in daily record are due to instrument malfunction or sensor being isolated. Unpublished maximum and minimum specific conductance data for period of daily record available in district office. November 1977 to April 1980, all water-quality data collected approximately 3.5 mi upstream. All data subsequent to April 1980 were collected at present site.

EXTREMES FOR PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: Maximum, 1,040 microsiemens/cm, Oct. 4, 1979; minimum, 64 microsiemens/cm, July 13, 1978.

WATER TEMPERATURE: Maximum, 31.5°C, July 19, 2003; minimum, 0.0°C on many days during winter months.

EXTREMES FOR CURRENT YEAR.--

WATER TEMPERATURE: Maximum, 31.5°C, July 19; minimum, 0.0°C, on many days.
