Background and Goals
Water quality testing found that dissolved oxygen and pH concentrations were sometimes outside the range required to support a healthy aquatic community in several bays and a harbor on the Texas coast. The affected segments were Matagorda Bay/Powderhorn Lake (Segment 2451), Tres Palacios/Turtle Bay (Segment 2452), Carancahua Bay (Segment 2456), and Conn Brown Harbor (Segment 2483A).
These coastal waters represent an ecologically important part of the Texas coast that include both freshwater and saltwater marshes along with open estuaries. The area has many diverse uses including recreation, production of oil and gas, cultivation of rice, sorghum, and cotton, livestock grazing, and commercial and residential developments.
The goal of this project was to assess water quality conditions in detail and to ensure the bays and harbor sustain a healthy aquatic community.
Project personnel informed the public about this project through a series of public meetings. The meetings were open to everyone.
