River gage is water-stage recorder.

Current datum of gage is 1,325.86 ft. above mean sea level. (NAVD88) Obtained Nov. 5, 2020 using Trimble R10 unit set over RM8 for 1-hour static survey processed by OPUS.

Old Datum of river gage is 1,325.66 ft above NGVD of 1929. Prior to Feb. 12, 1935, nonrecording gage at site 2.0 mi downstream at diffdrent datum. Feb. 12, 1935, to July 1, 1951, water-stage recorder, July 2, 1951, to Feb. 16, 1952, nonrecording gage, and Feb. 17, 1952, to Sept. 30, 1974, water-stage recorder at present site and at datum 2.00 ft higher. Floodway gage is water-stage recorder. Datum of floodway gage is 1,340.00 ft above NGVD of 1929 (levels by Wichita-Valley Center Flood Control Project).

REMARKS - Natural flow affected by diversions and groundwater withdrawals for irrigation and municipal supply. Satellite telemeter at river station and floodway station. Since May 1957, part of high-water flow bypasses river gage through floodway channel for which separate records are computed; figures representing combined discharge are given herein. Discharge through floodway occurred only on the days given in the following table:
