USGS Water-Year Summary 2023

07335700 KIAMICHI RIVER NEAR BIG CEDAR, OK

LOCATION - Lat 34°38'18", long 94°36'45" referenced to North American Datum of 1927, in SW 1/4 SE 1/4 sec.18, T.2 N., R.26 E., Le Flore County, OK, Hydrologic Unit 11140105, in Ouachita National Forest, on downstream side of right bank pier of bridge on State Highway 63, 0.2 mi downstream from Golden Brook, 1.1 mi upstream from Big Branch, 2.1 mi east of Big Cedar, and at mile 157.6.

DRAINAGE AREA - 39.6 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.

SURFACE-WATER RECORDS

PERIOD OF RECORD - October 1965 to current year.

GAGE - Water-stage recorder. Datum of gage is 887.58 above NAVD of 1988 determined by GNSS Level II Survey using Alltera network with RTK Trimble R-10 tied to RM-3 by USGS Personnel on 08-07-2019. Prior to 08-07-2019 Datum of gage was 886.97 ft above NGVD of 1929.

REMARKS -

10/01/2022 - 09/30/2023. Records rated fair. Quality of data for other periods can be obtained by contacting the Oklahoma-Texas Water Science Center.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge for period of record 27,400 ft³/s, May 19, 1990. Maximum gage height for period of record, 19.60 ft, May 19, 1990.

WATER-QUALITY RECORDS

PERIOD OF RECORD - 1907, 1962-1996, 2012 to current year.

REMARKS -

Accuracy Rating for Water Year 2023:

TEMPERATURE: Good; No fouling or calibration drift corrections were applied throughout this year per USGS and OTWSC policy. Minimal data loss occurred. Due to restrictions from this site installation, this sensor cannot be removed to undergo NIST checks. Instead, the OTWSC water quality specialist has suggested using a NIST-certified thermistor in the field multiple times throughout the year to verify the sensor accuracy at different temperature ranges. This method of NIST check did occur within this year, but water quality staff should make an effort to increase the frequency. The field check completed confirmed the sensor accuracy.

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