Oso Bay: A Community Project to Protect Recreational Uses
Coastal Basins: Bays and Estuaries, Nueces–Rio Grande Coastal Basin
Overview and Goals
Oso Bay is an enclosed, shallow body of water situated along the southern shore of Corpus Christi Bay, with a surface area of approximately seven square miles. The bay exchanges saltwater with Corpus Christi Bay and receives fresh water from Oso Creek, a stream whose flow is dominated by discharges subject to permit. Ecologically, Oso Bay provides habitat for many plants and animals, and plays an influential role in water purification and storm protection.
In 2002, water quality testing found that concentrations of bacteria are elevated in both the bay and the creek, which may pose a risk to people who swim or wade in them. Swimming and wading are called “contact recreation” in the state’s standards for water quality; the term refers to all recreation in which people come in direct contact with the water. The goal of this project is to reduce bacteria concentrations to within acceptable risk levels for contact recreation.
Staff from the Center for Coastal Studies at Texas A&M University–Corpus Christi are working with stakeholders to develop a plan for watershed improvement. Public meetings about this project are open to everyone.
The Coordination Committee is meeting monthly to complete the I-Plan.
All meetings at:
