Click to hide 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.

USGS Water-Year Summary 2022
LOCATION - Lat 36°21'19", long 94°46'34" referenced to North American Datum of 1927, in NW 1/4 SE 1/4 sec.30, T.22 N., R.24 E., Delaware County, OK, Hydrologic Unit 11070209, on left bank of county road bridge, 0.8 mi upstream from Spavinaw Creek, 2.3 mi east of Lake Eucha Bridge on U.S. Highway 10 and 59, and at mile 0.5.
DRAINAGE AREA - 59.1 mi². From automated delineation using 10-meter National Elevation Dataset digital elevation model data dated 10/01/2006 and Watershed Boundary Dataset dated 10/01/2006, using Albers Equal-Area Projection, North American Datum 1983.
REVISIONS HISTORY - WDR 2012: Drainage area.
PERIOD OF RECORD - July 30, 1998 to current year.
GAGE - Water-stage recorder. U.S. Geological Survey satellite telemeter at station. Datum of gage is 783.57 feet above NAVD of 1988. The NAVD of 1988 datum was determined by a level II GNSS Survey  REF FRAME: NAD_83(2011)(EPOCH:2010.0000)ITRF2014 (EPOCH:2020.5156)[NAVD88 (Computed using GEOID18)] by USGS on July 7, 2020 and tied to locally set GNSS hub. From July 07, 2020 to Sep. 30, 2021 the datum was listed as 781.70 feet above NAVD of 1988 and was based on an error in the calculations of the July 07, 2020 survey. Prior to July 7, 2020 the datum of gage was 783.52 ft above NGVD of 1929 as determined via topographic map by USGS. 

Quality of data for all periods can be obtained by contacting the Oklahoma-Texas Water Science Center

Estimated records are considered poor unless noted otherwise. 



Periodic samples, August 1991 to September 1993 and July 2001 to current year.

WATER TEMPERATURE: March 2005 to current year.

SPECIFIC CONDUCTANCE: March 2005 to July 2022. 

DISSOLVED OXYGEN: March 2005 to July 2022.

pH: March 2005 to July 2022.

TURBIDITY: March 2005 to current year.

COOPERATION - All analytical records were furnished by City of Tulsa Quality Assurance Laboratory, Tulsa, Oklahoma. 

Quality of data for all parameters recorded can be obtained for all periods by contacting the Oklahoma-Texas Water Science Center.

Interruptions in record were due to malfunctions of recording instrument. 

Samples collected periodically by the United States Geological Survey. All water-quality samples were analyzed at the City of Tulsa Quality Assurance Laboratory, Tulsa, Oklahoma. Supended sediment samples were analyzed by the U.S. Geological Survey. Specific conductance, pH, water temperature, air temperature, turbidity, and dissolved oxygen were determined in the field.


WATER TEMPERATURE: Maximum, 28.8°C, August 5,6, 2011; minimum, 2.2°C, February 9, 2011.

SPECIFIC CONDUCTANCE: Maximum, 347 microsiemens, August 28, 2006; Minimum, 43 microsiemens, March 18, 2008.

DISSOLVED OXYGEN: Maximum, 14.6 mg/l, February 6, 2014 and March 7, 2011 ; Minimum, 1.7 mg/l, July 14,16,18, 2006. 

pH: Maximum, 8.6 standard units, March 1-6, April 4-5,2016; Minimum, 6.6 standard units, July 17, 2021.

TURBIDITY: Maximum, 1,650 FNU, June 9, 2008; Minimum, <1 FNU, many days all water years.
