USGS Water-Year Summary 2023
LOCATION - Lat 36°09'55", long 86°43'17" referenced to North American Datum of 1927, Davidson County, TN, Hydrologic Unit 05130202, Water Quality Monitor: located on right bank 0.8 mi downstream from Mill Creek, upstream of Omohundro Filtration Plant, and at mile 193.7. DATUM updated December 23, 2011 to NAD83/NAVD88 gage height of 365.50 ft.
DRAINAGE AREA - 12,819 mi².
PERIOD OF RECORD - Sept. 17, 2010 to current year.
COOPERATION - Station instrumented and maintained in cooperation with Metropolitan Government of Nashville and Davidson County.
REMARKS - Flood-hydrograph stage only site. Flow is regulated by storage and power operations at numerous reservoirs above the station.
EXTREMES FOR PERIOD OF RECORD - Maximum gage height, 44.69 ft, February 24, 2019; minimum gage height, 18.10 ft, October 22, 2018
PERIOD OF RECORD - October 1996 to September 1999, October 2000 to current year.

SPECIFIC CONDUCTANCE: October 1996 to September 1999, October 2000 to current year.

pH: October 1996 to September 1999, October 2000 to current year.

WATER TEMPERATURE: October 1996 to September 1999, October 2000 to current year.

DISSOLVED OXYGEN: October 1996 to September 1999, October 2000 to current year.

INSTRUMENTATION - Four parameter water-quality sonde.
REMARKS - This site is directly affected by regulated releases upstream from Old Hickory Dam on the Cumberland River and J. Percy Priest Dam on the tributary Stones River and by unregulated flow from Mill Creek and other urban watersheds. Records for water temperature, specific conductance, and pH are good; and records for dissolved oxygen are fair, except for periods as noted. From April 27 to May 29, 2014 all records are fair. January 15, 2021 to April 28, 2021 all records are fair.
