Attention boaters! If you have a boat on Grapevine Lake, please know zebra mussels were discovered for the first time in the lake in June.
WHY ARE THEY BAD? Zebra mussels can have serious economic, recreational, and environmental impacts on Texas reservoirs and rivers. They can harm native aquatic species, affect water clarity, cause harmful algal blooms, cover shoreline rocks and litter beaches with sharp shells, clog water intakes, damage or increase maintenance on hydroelectric and other facilities using raw surface water, and damage boats and motors left in infested waters.
WHAT DOES THE LAW SAY? In Texas, it is unlawful to possess or transport zebra mussels, dead or alive. By law, boaters are required to drain all water from their boat and onboard receptacles before leaving or approaching a body of fresh water to prevent the transfer of zebra mussels and other invasive species. Zebra mussel larvae are microscopic and both adults and larvae can survive for days in or on boats transported from a lake. The requirement to drain applies to all types and sizes of boats whether powered or not: personal watercraft, sailboats, kayaks/canoes or any other vessel used on public waters.
WHAT SHOULD YOU DO? Before moving a boat from a lake with zebra mussels, please call the Texas Parks and Wildlife Department's 24/7 hotline at 512.389.4848 or email email@example.com so Texas Parks and Wildlife staff can provide guidance and support to reduce the risk of spreading zebra mussels.
