As the Fourth of July weekend approaches, Lake Texoma is expected to see increased boating activity, prompting state wildlife officials and local game wardens to remind boaters of the importance of preventing the spread of invasive species. The Texas Parks and Wildlife Department (TPWD) is urging all boaters to adhere to the practice of "clean, drain, and dry" their boats and equipment after each visit to the lake.
Zebra mussels, an invasive shellfish species, pose a significant threat as they attach to hard surfaces, potentially damaging boats and water infrastructure. They have been identified in 40 lakes across seven river basins in Texas. Daron Blackerby, a Grayson County Game Warden, noted that these mussels can clog pipes as they grow larger, leading to severe ecological consequences. Once established, zebra mussels cannot be controlled or eradicated from a lake.
Another invasive species to be aware of is giant salvinia, a free-floating fern that can create dense patches, complicating activities such as fishing, boating, and swimming. To combat the spread of these species, boaters are required to drain all water from their boats, including any bait buckets, and to remove invasive plants before leaving or approaching another body of fresh water. Failure to comply with these regulations can result in a Class C Misdemeanor.
TPWD recommends that boaters follow three essential steps: First, clean the boat and trailer by removing all plants, mud, and debris. Second, drain all water from the boat and gear by pulling the drain plug. Lastly, allow the boat to dry completely for at least a week, or use a high-pressure rinse if a week is not feasible.
Boaters who have stored their vessels in lakes known to have invasive mussels should contact TPWD at (512) 389-4848 before moving their boats, as they may be at high risk of infestation.
