USGS Water-Year Summary 2021
08155500 Barton Springs at Austin, TX
LOCATION - Lat 30°15'48", long 97°46'16" referenced to North American Datum of 1927, Travis County, TX, Hydrologic Unit 12090205, at ground-water well (YD 58-42-903), on right bank 0.4 mi upstream from Barton Springs Road bridge over Barton Creek, 0.7 mi upstream from mouth, and 1.8 mi southwest of the State Capitol Building in Austin.
DRAINAGE AREA - Not applicable.
SURFACE-WATER RECORDS
PERIOD OF RECORD - Nov. 1894 to Apr. 1917 and Oct. 1918 to Feb. 1978 (discharge measurements only), May 1917 to Sept. 1918 (published as "Barton Creek"), Mar. 1978 to Sept. 1994 (daily mean discharge), Oct. 1994 to Sept. 1999 (discharge at 1200 hours), Oct. 1999 to current year.
GAGE - Water-stage recorder. Datum of gage, at ground-water well (YD-58-42-903), is 462.34 ft above NGVD of 1929. May 1917 to Sept. 1918, nonrecording gage at site 1,000 ft downstream at different datum. Satellite telemeter at station.
REMARKS - Records poor. Only springflow from the Edwards and associated limestones in the Balcones Fault Zone is published for this station. Operation of Barton Springs pool significantly affects level recorded in well. Pool is periodically drained for cleaning and allowed to fill after cleaning operations. Under normal conditions gage height is in direct relation with discharge. Determination of flow from spring is considered best when pool/well level has stabilized at 1200 hrs. From Oct. 1, 1994, to Sept. 30, 1999, daily flow was determined using the recorded level at 1200 hrs. Beginning Oct. 1, 1999, flow is determined from daily mean. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.
WATER-QUALITY RECORDS
PERIOD OF RECORD - CHEMICAL DATA: Nov. 1969, Dec. 1978 to current year. BIOCHEMICAL DATA: May 1978 to current year. BIOLOGICAL DATA: Nov. 1969, July 1978 to July 2003, Feb. 2007 to Mar. 2010. RADIOCHEMICAL DATA: Jan. 1980 to May 1981. STABLE ISOTOPES DATA: Nov. 2008 to Mar. 2010, Nov. 2011 to Dec. 2011. PESTICIDE DATA: July 1978 to July 1982, Oct. 1984, June 1987 to Nov. 1993, May 2000 to current year. ORGANICS, OTHER DATA: Feb. 2009 to Feb. 2010. SEDIMENT DATA: May 1999 to Apr. 2010. SEDIMENT CHEMISTRY DATA: May 2000 to Oct. 2004.
PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: June 2003 to current year. pH: Oct. 2005 to current year. WATER TEMPERATURE: June 2003 to current year. DISSOLVED OXYGEN: July 2003 to current year. TURBIDITY: June 2003 to current year. fDOM: Nov. 2019 to current year. NITRATE PLUS NITRITE: Dec. 2019 to current year.
COOPERATION - City of Austin, Austin, TX.
INSTRUMENTATION - Multi-parameter water-quality monitor.
REMARKS - Interruptions or periods of missing record may be due to instrument failure, negative values, or data corrections exceeding allowable criteria, which were deleted. Minimum and maximum extremes may have occurred during period of missing record. The turbidity record is rated poor for values less than 5 FNU due to sensor limitations.
EXTREMES FOR PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Maximum, 734 microsiemens/cm, July 21, 22, Aug. 12, 2009; minimum, 129 microsiemens/cm, Oct. 13 2014. pH: Maximum, 8.0 standard units, Oct. 13, 2013, Sep. 2, 2009; minimum, 6.5 standard units, June 18, 2009, June 26, 2013. WATER TEMPERATURE: Maximum, 22.5C, Oct. 13, 2013; minimum, 17.9C, Jan. 17, 2010. DISSOLVED OXYGEN: Maximum, 8.3 mg/L, Jan. 17, 2010 and Oct. 13, 2013; minimum, 4.0 mg/L, July 25, 26, 2009. TURBIDITY: Maximum, 690 FNU, Oct. 14, 2013; minimum, 0.0 FNU, on many days. fDOM: Maximum, 48.9 QSE, May 26, 2020; minimum, 3.20 QSE, May 12, 2020.
