COLORADO RIVER MAIN STEM

09163500 COLORADO RIVER NEAR COLORADO-UTAH STATE LINE-Continued

(National Water-Quality Assessment Program station)

WATER-QUALITY RECORDS

PERIOD OF RECORD.--October 1969 to current year. For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=09163500

PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: October 1979 to current year.

WATER TEMPERATURE: October 1979 to current year.

INSTRUMENTATION.--Water-quality monitor since October 1979.

REMARKS.-- Daily records of specific conductance are excellent, except May 20 to June 10, which are good, Mar. 27 to Apr. 9, which are fair, and Oct. 1-2, Oct. 30 to Dec. 4, and June 11 to July 14, which are poor. Daily records of water temperature are excellent. October 1979, water-quality data collection was moved 5.5 mi upstream to this site from previous site 09163530. Water-quality records for this site are considered to be equivalent to data obtained at old site. Data from the old site are stored with this station. Prior to October 1995, unpublished maximum and minimum specific conductance data available in district office.

Note: Suspended Sediment Discharge table: a sampler code of 3009 is a D-74 suspended sediment sampler; a code of 3039 is a D-77 water-quality sampler; a code of 3045 is a DH-81 depth-integrating sampler; a code of 3053 and 3054 is a D-95 depth-integrating sampler. Suspended sediment concentrations associated with a sampler type coded 3039 or 3053 were determined from a subsample split of a composite sample.

EXTREMES FOR PERIOD OF DAILY RECORD.--

SPECIFIC CONDUCTANCE: Maximum 1,940 microsiemens/cm, Aug. 13, 1981; minimum, 277 microsiemens/cm, June 11, 1985.

WATER TEMPERATURE: Maximum, 27.6°C, July 19, 2003; minimum, -0.3°C on several days in Dec. 1996 and Jan. 1997.

EXTREMES FOR CURRENT YEAR.--

SPECIFIC CONDUCTANCE: Maximum, 1,680 microsiemens/cm, Feb. 13; minimum, 332 microsiemens/cm, June 3.

WATER TEMPERATURE: Maximum, 27.6°C, July 19; minimum, 0.0°C, Dec. 27, 28, 29, Jan. 1, 4.
