PERIOD OF RECORD.--November 1975 to August 1981, April 1996 to current year.

PERIOD OF DAILY RECORD.--
	SPECIFIC CONDUCTANCE:  July 1997 to September 1997.
	pH:  July 1997 to September 1997.
	WATER TEMPERATURE:  October 1996 to September 1997.

REMARKS.--The following data are for trace elements and other constituents that were part of the suspended-
	sediment fraction of the water sample.  Suspended sediments were dewatered using a continuous flow centrifuge,
	dried, and analyzed directly for total metals using a nitric, hydrofluoric, perchloric acid digestion.  Whole
	water contributions by the suspended sediment were then calculated using the suspended-sediment concentration
	in kilograms per liter (kg/L) and the analyte concentration in milligrams per kilogram (µg/kg) from the direct
	analysis of the suspended sediments, resulting in micrograms per gram (µg/g) concentrations.  Values reported
	in percent are the percent of that constituent in the suspended sediment.  When no trace element was detected
	in the sample, the default reporting value is the method detection limit preceded by a less-than sign (<).
