Prior to September 8, 2011 the continuous water-quality data displayed for this site were prepared according to the protocols ( Texas Commission on Environmental Quality, 2010) of the cooperator rather than the protocols (Wagner and others, 2006) of USGS. Some differences are present when comparing these data to other continuous water-quality monitoring sites maintained by USGS.
