Join WTS for an informative presentation on new state-listed mussel regulatory requirements and emerging zebra mussel issues. Understanding these requirements help the planning of future projects and eliminate avoidable costly delays.

State-Listed Threatened Mussels and Regulatory Requirements: What You Need to Know to Avoid Project Delays






In 2010, Texas Parks and Wildlife Department (TPWD)listed 15 native freshwater mussels as “state threatened” species. State-listed mussels occur in the Red, Neches, Sabine, San Jacinto, Trinity, Colorado, Guadalupe, San Antonio, Nueces-Frio, Brazos, Rio Salado, Pecos, and Rio Grande river basins. State law prohibits take (i.e., harm, etc.) of state-listed species. 

Projects that may have impacts to rivers, tributaries, and/or reservoirs within the state of Texas, may require mussel presence/absence surveys and associated relocation activities, if applicable, prior to construction.  These activities should be conducted by persons possessing a permit issued by TPWD, and plans for potential relocations, if required, must be approved by TPWD.  In addition, zebra mussel populations have been recently documented at various locations within the Red, Trinity, and Brazos river basins; therefore, zebra mussel presence should be taken into consideration when performing TPWD-required native mussel survey and relocation activities.
