USGS Water-Year Summary 2023
06890900 DELAWARE RIVER AT PERRY, KS
LOCATION - Lat 39°04'30", long 95°24'13" referenced to North American Datum of 1927, in NE 1/4 SW 1/4 SW 1/4 sec.22, T.11 S., R.18 E., Jefferson County, KS, Hydrologic Unit 10270103, 0.5 mi west of Perry on Bridge Street at right downstream end of bridge, and at mile 1.4.
DRAINAGE AREA - 1,141 mi² of which 1,116.83 mi² probably is noncontributing.
REVISIONS HISTORY - WDR KS-83-1: 1982.
SURFACE-WATER RECORDS
PERIOD OF RECORD - March 1969 to current year. Prior to September 2003 published as "below Perry Dam."
GAGE - Acoustic velocity recorder. Datum of gage is 800.00 ft above NGVD of 1929, from topographic map. Prior to May 5, 2003, at site 4.4 mi upstream at same datum. Prior to May 5, 2003, water-stage and discharge records from reservoir elevations and gated outflow structure.
COOPERATION - Reservoir elevation-discharge ratings for reservoir outflow gates and gate operation logs furnished by U.S. Army Corps of Engineers.
REMARKS - Flow completely regulated since 1969 by Perry Lake (station 06890898). After May 5, 2003, discharge computed by velocity-index method. This station is located near the confluence of the Kansas River and discharge computed can, at times, be affected by backwater. During periods of backwater, water velocity that is continuously measured will be negative and therefore discharge computed will be negative. Satellite telemeter at station.
WATER-QUALITY RECORDS
PERIOD OF RECORD - October 2012 to current year.
PERIOD OF DAILY RECORD - WATER TEMPERATURE: October 2012 to September 2013.
REMARKS - Interruptions in record are due to ice conditions or malfunction of the recording instrument or sensors or the stream being dry.
EXTREMES FOR PERIOD OF DAILY RECORD - WATER TEMPERATURE: Maximum, 30.2°C, July 10, 2013; minimum, 0.3°C Jan. 3, 2013.
