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: February 2010 to current year.
GAGE-HEIGHT: February 2010 to current year.
DISCHARGE: February 2010 to current year.
GAGE-HEIGHT: February 2010 to current year.
GAGE - Satellite telemetry with a water-stage recorder and a continuous water-quality monitor. Datum of gage is 851.75 feet above the North American Vertical Datum (NAVD) of 1988.

For period:10/01/2015-09/30/2016: Continuous water temperature and specific conductance records are good, turbidity record is poor.
For period:10/01/2016-09/30/2017: Continuous water temperature and specific conductance records are good, turbidity record is poor.
For period:10/01/2017-09/30/2018: Continuous water temperature and specific conductance records are good, turbidity record is poor.
For period:10/01/2018-09/30/2019: Continuous water temperature and specific conductance records are good, turbidity record is poor.
For period:10/01/2019-09/30/2020: Continuous water temperature and specific conductance records are good, turbidity record is poor.
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). Hydrologic event 9 indicates a routine sample while J designates a storm event sample. Laboratory chemical analyses are by RTI Laboratory, Livonia, MI. Laboratory sediment analyses are by the U.S. Geological Survey, Kentucky Sediment Laboratory. Field determinations of discharge, gage height, specific conductance, pH, water temperature, turbidity, barometric pressure, air temperature, and dissolved oxygen are by the U.S. Geological Survey.
