Beginning July 1, boaters must drain all water from their boat and on-board receptacles before leaving or approaching a body of fresh water anywhere in Texas. The new Texas Parks and Wildlife Department regulation is designed to help combat the further spread of zebra mussels and other invasive species. It 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. The regulation requires the draining of livewells, bilges, motors, and any other receptacles or water-intake systems coming into contact with public waters. Live fish, including personally caught live bait, cannot be transported from the water body where the fish were caught in or aboard a vessel in water from the water body where the fish were caught. Personally caught live bait can be used in the water body where it was caught. Anglers are allowed to transport and use commercially purchased live bait if they have a receipt that identifies the source of the bait. Any live bait purchased from a location on or adjacent to a public water body that is transported in water from that water body can only be used as bait on that same water body. Anglers participating in a fishing tournament confined to one water body may transport live fish in water from that single water body to an identified off-site weigh-in location, but all water must be drained and properly disposed of before leaving that location. Anglers are required to possess documentation provided by tournament organizers that identify them as participants in the tournament. Movement from one access point to another on the same lake during the same day does not require draining, and there is an exception for governmental activities and emergencies. Marine sanitary systems are not covered by these regulations. Texas Parks and Wildlife Department and a coalition of partners are working to slow the spread of zebra mussels by reminding boaters to Clean, Drain and Dry their vessels before traveling from one lake to another. The partners in this effort include: North Texas Municipal Water District, Tarrant Regional Water District, City of Dallas Water Utilities Department, Trinity River Authority, San Jacinto River Authority, Sabine River Authority, Brazos River Authority, Guadalupe-Blanco River Authority, Lower Colorado River Authority, Upper Trinity Regional Water District, Canadian River Municipal Water Authority, City of Grapevine, Water Oriented Recreation District of Comal County, and the Lady Bird Johnson Wildflower Center.
