WATER-QUALITY RECORDS
PERIOD OF RECORD.--August 19, 1992, to current year.
PERIOD OF DAILY RECORD.--
SUSPENDED-SEDIMENT DISCHARGE: November 12, 1992, to current year.
INSTRUMENTATION.--Refrigerated water-quality pumping sampler since November 12, 1992.
REMARKS.--Suspended-sediment samples were collected by pumping sampler. Pumped samples were collected for every
1-ft rise and 2-ft drop in stage. Sediment samples were also collected by a technician intermittently throughout
the year. Suspended-sediment loads were calculated using the mean-interval method (Porterfield, George, 1972,
Computation of Fluvial-Sediment Discharge: U.S. Geological Survey, Techniques of Water-Resources Investigations,
book 3, chap. C3, 66 p.). For days with unsteady concentration, discharge, or both, the day was subdivided into
quarter-hour intervals and the daily load was calculated by summing the loads for these quarter-hour intervals.
This required interpolation between measured and estimated concentrations.
EXTREMES FOR PERIOD OF DAILY RECORD.--
SEDIMENT CONCENTRATIONS: Maximum daily mean, 708 mg/L, May 9, 1996; minimum daily mean, 3 mg/L, Feb. 14, 20, 21,
1995.
SEDIMENT LOADS: Maximum daily, 5,740 tons, June 3, 1997; minimum daily, 0.22 ton, Sep. 25, 1994.
EXTREMES FOR CURRENT YEAR.--
SEDIMENT CONCENTRATIONS: Maximum daily mean, 453 mg/L, June 2; minimum daily mean, 10 mg/L, Mar. 31.
SEDIMENT LOADS: Maximum daily, 5,740 tons, June 3; minimum daily, 0.25 ton, Sept. 30.
