TR-524 Characterizing the Middle Yegua, Davidson Creek and Deer Creek Watersheds Final Report
Authors: Stephanie deVilleneuve
Middle Yegua Creek, Davidson Creek and Deer Creek have all been identified as impaired for elevated concentrations of Escherichia coli (E. coli) in the 2018 Texas Integrated Report of Surface Water Quality for the Clean Water Act Sections 305(b) and 303(d). Davidson Creek was also listed in the 2018 Texas Integrated Report as impaired for depressed dissolved oxygen. Elevated levels of E. coli have been identified in the Middle Yegua Creek watershed since as early as 2010. For the Davidson Creek watershed, elevated bacteria levels were first identified in 2002 and depressed dissolved oxygen in 2010. For the Deer Creek watershed, the bacteria impairment was first identified in 2006. The primary objectives of this project were to evaluate existing data within the project areas, identify causes and sources of pollution, engage local stakeholders, provide educational programs and assess water quality. The result of meeting these objectives was a thorough characterization of the Middle Yegua Creek, Davidson Creek and Deer Creek watersheds which will help stakeholders with future watershed planning efforts.
