TR-534 Mission and Aransas Rivers Watershed Protection Plan
Authors: Texas Water Resources Institute
Water quality monitoring indicates that sections of the Mission and Aransas rivers and Poesta Creek do not meet water quality standards for recreation because of elevated levels of Escherichia coli (E. coli) and Enterococci. The tidal segments of the Mission and Aransas rivers were first identified as impaired in the 2004 Texas Integrated Report and 303(d) List, while Aransas River Above Tidal and Poesta Creek segments were first identified as impaired in the 2014 Texas Integrated Report and 303(d) List. With the water quality impairments comes a need to plan and implement actions that restore water quality and ensure safe and healthy water for stakeholders. To meet this need, an assessment and planning project was undertaken to develop the Mission and Aransas Rivers Watershed Protection Plan.
