07191500 NEOSHO RIVER NEAR CHOUTEAU, OK
LOCATION - Lat 36°13'46", long 95°10'57" referenced to North American Datum of 1927, in SE 1/4 NW 1/4 sec.09, T.20 N., R.20 E., Mayes County, OK, Hydrologic Unit 11070209, in Robert S. Kerr Dam about 100 ft from left end of dam, 2.2 mi northwest of Locust Grove, 10.0 mi northeast of Chouteau, and at mile 47.2.
DRAINAGE AREA - 11,580 mi². revised. 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.
- WDR OK-86-1: 1979. WDR 2012: Drainage area.
PERIOD OF RECORD - October 1937 to September 1950, October 1963 to current year.
GAGE - Water-stage recorder. Current datum in use is 554.28 NAVD88. Current datum determined by GNSS Level II REF FRAME: NAD_83(2011)(EPOCH:2010.0000) ITRF2014 (EPOCH:2022.6458)[NAVD88 (Computed using GEOID18)] Tied to GNSS 203. Prior to 10/01/2022 datum in use was 554.00 ft above NGVD of 1929 (levels by U.S. Army Corps of Engineers). Prior to Apr. 3, 1941, nonrecording gage at bridge on State Highway 33, 8.2 mi downstream, at datum 17.63 ft lower. Apr. 3, 1941 to Sept. 30, 1950, and Oct. 1963 to Apr. 6, 1964, at site 2.5 mi downstream, at datum 2.17 ft lower. Supplemental water-stage recorder Oct. 4, 1963, to July 10, 1973, at site 8.2 mi downstream. Some regulation since 1940 by Lake O' The Cherokees (station 07190000), and completely regulated since 1963 by Lake Hudson (station 07191400).
EXTREMES FOR PERIOD OF RECORD - Minimum daily discharge for period of record was caused by closure of Robert S. Kerr Dam. Maximum discharge for period of record, 400,000 ft³/s, May 20, 1943, gage height 45.00 ft, site and datum then in use, rating curve extended above 140,000 ft³/s on basis of slope-area measurement of peak flow. The maximum peak stage, since the impoundment of Lake Hudson, is 43.81. This value of 43.81 occurred during backwater on Dec. 29, 2015.
