USGS Water-Year Summary 2019
07241550 NORTH CANADIAN RIVER NEAR HARRAH, OK
LOCATION - Lat 35°30'01", long 97°11'37" referenced to North American Datum of 1927, in SW 1/4 NW 1/4 sec.22, T.12 N., R.1 E., Oklahoma County, OK, Hydrologic Unit 11100302, on left bank downstream side county road bridge, 2.2 mi northwest of Harrah, 3.8 mi downstream from Choctaw Creek, and at mile 230.0.
DRAINAGE AREA - 13,775 mi² of which 3,497 mi² probably is noncontributing. 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.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1968 to current year.
GAGE - Water-stage recorder. Datum of gage is 1055.69 ft above NGVD of 1929.
REMARKS - 10/01/2013 - 09/30/2014: records fair. 10/01/2014 - 09/30/2015: records good. 10/01/2015 - 09/30/2016: records fair. 10/01/2016 - 09/30/2017: records good. 10/01/2017 - 09/30/2018: records fair. 10/01/2018 - 09/30/2019: records fair. Flow regulated by Canton Lake (station 07238500) and by Lake Overholser (station 07240500) where diversions are made into Lake Hefner Canal (station 07240000). Low flow sustained in part by sewage effluent.
WATER-QUALITY RECORDS
PERIOD OF RECORD -

WATER TEMPERATURE: October 1968 to current year.

SPECIFIC CONDUCTANCE: October 1968 to current year.

pH: October 1988 to current year.

DISSOLVED OXYGEN: October 1988 to current year.

REMARKS -

Accuracy rating of the record for the 2019 Water Year:

WATER TEMPERATURE: Excellent; no data corrections and few data gaps.

SPECIFIC CONDUCTIVITY: Fair; Frequent fouling and calibration drift calibrations. Some with large magnitudes. Some data gaps. 

pH: Fair; Large portions of deleted data, but most fouling and calibration drift corrections were Good. Several manual corrections that introduce unknown error. A few large data gaps. 

DISSOLVED OXYGEN: Fair; Many fouling and calibration drift corrections, some of fairly large magnitude. Some large data gaps. 

Interruptions in record were due to malfunctions of the recording instrumentation or corrections to the data that exceeded allowable limits.
