Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

SURFACE-WATER RECORDS
PERIOD OF RECORD -
DISCHARGE: March 2012 to current year
GAGE-HEIGHT: March 2012 to current year
DISCHARGE: March 2012 to current year
GAGE-HEIGHT: March 2012 to current year
GAGE - Satellite telemetry with a water-stage recorder and continuous water-quality monitor. Datum of gage is 935.10 feet above NAVD88.

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). Laboratory chemical analyses are by RTI Laboratory, Livonia, MI. Laboratory sediment analyses are by the U.S. Geological Survey, KY Sediment Laboratory. Field determinations of discharge, microbiology, specific conductance, pH, water temperature, turbidity, barometric pressure, air temperature, and dissolved oxygen are by the U.S. Geological Survey.
