					WATER-QUALITY RECORDS


PERIOD OF RECORD.--1965-1977, 1988, May 6, 1992, to current year.
PERIOD OF DAILY RECORD.--
   SUSPENDED-SEDIMENT DISCHARGE: November 12, 1992, to current year.
REMARKS.--Suspended-sediment samples were collected by a local observer approximately once per day. Sediment samples 
were also collected by a pumping sampler until January 27. Pumped samples were collected for every 1-ft rise and 
2-ft drop in stage. 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, 844 mg/L, June 3, 1997; minimum daily mean, 1 mg/L,                       
Oct. 25-27, 1995.
  SEDIMENT LOADS: Maximum daily, 45,500 tons, June 3, 1997; minimum daily, 0.25 ton, Oct. 11, 1993.
EXTREMES FOR CURRENT YEAR.--
  SEDIMENT CONCENTRATIONS: Maximum daily mean, 844 mg/L, June 3; minimum daily mean, 3 mg/L, Nov. 9.
  SEDIMENT LOADS: Maximum daily, 45,500 tons, June 3; minimum daily, 0.59 ton, Nov. 6.
