USGS Water-Year Summary 2021
08170990 Jacobs Well Spring near Wimberly, TX
LOCATION - Lat 30°02'04", long 98°07'34" referenced to North American Datum of 1983, Hays County, TX, Hydrologic Unit 12100203, located 100 feet from the right bank of Jacobs Well Spring.
DRAINAGE AREA - Not applicable. This is a springflow station.
PERIOD OF RECORD - Apr. 2005 to current year. PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Nov. 2005. BIOCHEMICAL DATA: Nov. 2005. PESTICIDE DATA: Nov. 2005. RADIOCHEMICAL DATA: Nov. 2005.
GAGE - Water-stage and water-velocity recorder. Datum of gage is 922.84 ft above NGVD of 1929. Satellite telemeter at station.
REMARKS - Records poor. Only springflow from the Trinity and associated limestones is published for this station. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.
PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Apr. 2005 to current year. WATER TEMPERATURE: Apr. 2005 to current year. TURBIDITY: June 2005 to current year.
COOPERATION - Guadalupe-Blanco River Authority, Seguin, TX.
INSTRUMENTATION - Three 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, for values less than 5 FNU, is rated poor due to sensor limitations. Spikes in turbidity are due to storm events. The continuous water-quality data displayed for this site prior to June 12, 2009 was prepared according to the protocols of the cooperator rather than the protocols (Wagner and others, 2006) of USGS.
EXTREMES FOR PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Maximum, 625 microsiemens/cm, Dec. 6, 2011; minimum, 219 microsiemens/cm, Feb. 4, 2012. WATER TEMPERATURE: Maximum, 21.6C, Sept. 8, 2010 , September 10, 2018 ; minimum, 17.1C, Feb. 12, 13, 2010. TURBIDITY: Maximum, 1,130 FNU, Feb. 4, 2012; minimum, 0.0 FNU on multiple days.
