  • Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
  • For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
  • For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
  • For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
  • Not all sites have reports available for every water year.

USGS Water-Year Summary 2023
06805000 Salt Creek Near Ashland, Nebr.
LOCATION - Lat 41°03'06", long 96°20'19" referenced to North American Datum of 1983, in sec.31, T.13 N., R.10 E., Saunders County, NE, Hydrologic Unit 10200203, 1.7 mi northeast of Ashland, 0.8 mi below confluence with Wahoo Creek, and at mile 2.2.
DRAINAGE AREA - 1,640 mi² of which 52 mi² probably is noncontributing.
PERIOD OF RECORD - March 2012 to current year (seasonal stage record only).
GAGE - Water-stage recorder with satellite telemetry. Datum of gage is 1,040.00 ft above National Geodetic Vertical Datum of 1929.
REMARKS - Accuracy of gage height records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, gage height records fair to good, unless otherwise noted. Seasonal Water Year record generally collected from October 1-31 and April 1 to September 30.

Maximum gage height, 22.10 ft. , March 14, 2019.

PERIOD OF DAILY RECORD - WATER TEMPERATURE: August 2007 to present (seasonal records only). SPECIFIC CONDUCTANCE: August 2007 to present (seasonal records only). TURBIDITY: August 2007 to present (seasonal records only). DISSOLVED OXYGEN: August 2007 to present (seasonal records only).

Seasonal deployment of a continuous water-quality monitor. Measured parameters include water temperature, specific conductance, dissolved oxygen, turbidity, and nitrate. Turbidity measurements conform to ISO 7027 standards. Dissolved oxygen measurements were collected using a luminescent sensor. Nitrate measurements were collected using a Hach Nitratax sensor with 2 mm wavelength sensing.

YSI Exo probes used at this site include:

Wiped Conductance probe (USGS Parameter Code 00095, method code SC001).

Dissolved Oxygen probe (USGS Parameter Code 00300, method code LUMIN).

Turbidity probe (USGS Parameter Code 63680,

YSI 6600-method code TS087 was used prior to 1/1/2016, and then from 1/1/2017 to 1/1/2019.

 YSI Exo2-method code TS213 was used used from 1/1/2016 to 1/1/2017, and then from 1/1/2019 to the present.


These extremes may have been exceeded during non-measured periods.

WATER TEMPERATURE: Maximum, 33.5°C, August 22, 2023; minimum, 1.1°C, March 26, 2013. 

SPECIFIC CONDUCTANCE: Maximum, 6,240 uS/cm, October 4, 2023; minimum, 139 uS/cm, August 24, 2016.

DISSOLVED OXYGEN: Maximum, 23.4 mg/L, July 3, 2012; minimum, 0.1 mg/L, April 14, 2014.

TURBIDITY: USGS Parameter Code 63680 in formazin nephelometric units (FNU),

A YSI 6600 turbidity probe was used for data prior to January 1, 2016, and during the period of 1/1/2017 to 1/1/2019 (USGS Parameter Code 63680, method code TS087).

Extremes for this period include a maximum, >1900 FNU, September 14, 2010; minimum, 2 FNU, September 17, 2015.

A YSI Exo was used for data from 1/1/2015 to 1/1/2016, and data 2019 to the present, a YSI EXO was used. (USGS Parameter Code 63680, method code TS213).

Extremes for this period include a maximum, 2220 FNU, July 12, 2016; minimum, 4.3 FNU, April 20, 2022.
