Texas Parks and Wildlife is reminding paddlers and boaters this summer to clean, drain, and dry all watercraft to protect lakes from invasive species such as giant salvinia and zebra mussels.
“Taking just a few minutes to clean, drain and dry boats can make a huge difference in our efforts to prevent further spread of this highly damaging species and harm to Texas lakes,” said Monica McGarrity, TPWD senior scientist for aquatic invasive species.
Giant Salvinia, a highly invasive, free-floating aquatic fern that can double its coverage area in a week, is one of the major threats to Texas lakes. It produces thick surface mats that make fishing, boating, or swimming nearly impossible.
Giant Salvinia is present on 27 East Texas lakes and numerous rivers, creeks, and marshes between Houston and Beaumont.
Texas Parks and Wildlife is urging boaters to clean, drain, and dry boats and gear before traveling from one body of water to another.
Remove plants, mud, and debris; drain all water from the boat and gear. Once back home, open the compartments and allow everything to dry completely.
TPWD and partners monitor for invasive species in Texas lakes, but anyone who spots them on boats, trailers, or equipment that is being moved can help prevent new introductions by reporting the sighting to TPWD at 512-389-4848.
Anyone who finds invasive species, such as zebra mussels, in lakes where they haven’t been seen before can help identify new introductions by emailing photos and location information to aquaticinvasives@tpwd.texas.gov.
