USGS Water-Year Summary 2018
06795500 Shell Creek near Columbus, Nebr.
LOCATION - Lat 41°31'34", long 97°16'54" referenced to North American Datum of 1983, in NE 1/4 NW 1/4 sec.23, T.18 N., R.1 E., Platte County, NE, Hydrologic Unit 10200201, on right bank 10 ft upstream from county road bridge, 1 mi upstream from Loseke Creek, 7 mi northeast of Columbus, and at mile 32.2.
DRAINAGE AREA - 294 mi².
REVISIONS HISTORY - WDR NE-94-1: Drainage Area.
PERIOD OF RECORD - August 1947 to September 1975, October 1977 to current year.
GAGE - Water-stage recorder with satellite telemetry. Elevation of gage is 1,435 ft above National Geodetic Vertical Datum of 1929, from topographic map.
REMARKS - Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, records fair except for estimated daily discharges, which are poor, unless otherwise noted.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of June 2, 1947, reached a stage of 21.7 ft, from floodmark, discharge, 4,600 ft³/s. According to local residents, this was the highest occurrence since 1912.
EXTREMES FOR PERIOD OF RECORD - Maximum peak flow, 11,200 ft³/s, May 30, 2008, gage height, 22.06 ft. Maximum peak stage, 22.76 ft, June 17, 1990, discharge, 8,000 ft³/s.
PERIOD OF RECORD - Water years 1974-1975, 1977, 1989-1990, 1992-1995, 2003, 2008 to October 2012, March to October 2014.
PERIOD OF DAILY RECORD - WATER TEMPERATURE: March 2008 to October 2012 (seasonal records only). March 2014 to October 2015(seasonal records only). SPECIFIC CONDUCTANCE: March 2008 to October 2012 (seasonal records only). March 2014 to October 2015(seasonal records only). TURBIDITY: March 2008 to October 2012 (seasonal records only). March 2014 to October 2015(seasonal records only). DISSOLVED OXYGEN: March 2008 to October 2012 (seasonal records only). March 2014 to October 2015(seasonal records only).
INSTRUMENTATION - Seasonal deployment of a continuous water-quality monitor. Measured parameters include water temperature, specific conductance, dissolved oxygen, and turbidity. Turbidity measurements conform to ISO 7027 standards and were made using a Yellow Springs International (YSI) 6136 sensor. Dissolved oxygen measurements were collected using an optical dissolved oxygen sensor.
EXTREMES FOR PERIOD OF RECORD - Extremes computed from approved periods of record, and may have been exceeded during non-measured periods. WATER TEMPERATURE: Maximum, 33.3°C, July 25, 2012; minimum, 1.4°C, March 21, 2010. SPECIFIC CONDUCTANCE: Maximum, 996 uS/cm, September 11, 2011; minimum, 119 uS/cm, September 16, 2016. DISSOLVED OXYGEN: Maximum, 26.1 mg/L, August 29, 2008; minimum, 0.1 mg/L, June 5, 2008. TURBIDITY: Maximum, >1,000 FNU, sensor limit exceeded numerous times, typically during periods of runoff; minimum, 3.7 FNU, September 19, 2011.
