PERIOD OF DAILY RECORD -
SPECIFIC CONDUCTANCE: September 2005 to July 2014 (discontinued).

WATER TEMPERATURE: September 2005 to July 2014 (discontinued).

TURBIDITY: September 2005 to July 2014 (discontinued).
INSTRUMENTATION - Satellite telemetry with a continuous water-quality monitor and an automatic refrigerated sampler.
REMARKS -
10/01/2013-07/29/2014: Water temperature and specific conductance records are good. Turbidity record is fair. Data for parameter code 63680 (turbidity) were collected using a probe with the following specifications: turbidity, water, monochrome near infra-red LED light, 780-900 nm, detection angle 90 +/-2.5 degrees, FNU (Formazin Nephelometric Units). Prior to October 1, 2004, turbidity data were published using parameter code 00076: turbidity, water, unfiltered, NTU (Nephelometric Turbidity Units).

Hydrologic event 9 indicates a routine sample while J designates a storm event sample. Laboratory chemical analyses are by the RTI Laboratories, Livonia, MI and Test America Laboratory, Denver, CO. Laboratory sediment analyses are by the U.S. Geological Survey, Kentucky Sediment Laboratory. Field determinations of discharge, specific conductance, pH, water temperature, turbidity, barometric pressure and dissolved oxygen are by the U.S. Geological Survey.
