WATER-QUALITY RECORDS
PERIOD OF RECORD.--May 4, 1992, to current year.
PERIOD OF DAILY RECORD.--
SUSPENDED-SEDIMENT DISCHARGE: October 1, 1992, to current year.
INSTRUMENTATION.--Refrigerated water-quality pumping sampler since October 1, 1992.
REMARKS.--Water-quality samples were collected by equal-width-increment (EWI) sampling method, approximately once
per month. Suspended-sediment samples and seasonal-event water-quality samples were collected by pumping sampler.
Pumped samples were collected for every 0.5-ft rise and 1-ft drop in stage. Sediment samples were also collected
by a local observer approximately once per day. 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, 601 mg/L, Jan. 26, 1994; minimum daily mean, 1 mg/L, Oct. 11, Nov. 3,
4, 1995, Aug. 7, and Oct. 25, 1996.
SEDIMENT LOADS: Maximum daily, 1,610 tons, Jan. 26, 1994; minimum daily, 0.00 ton, on many days during 1993, 1994,
and 1995 and on several days during 1996 and 1997.
EXTREMES FOR CURRENT YEAR.--
SEDIMENT CONCENTRATIONS: Maximum daily mean, 543 mg/L, Mar. 2; minimum daily mean, 1 mg/L, Oct. 25.
SEDIMENT LOADS: Maximum daily, 948 tons, June 2; minimum daily, 0.00 ton, on several days during the year.
