Lake Fork confirmed with giant salvinia


Texas Parks and Wildlife Department (TPWD) released an announcement Tuesday, Nov. 14, that Lake Fork — one of the nation’s premier bass fishing destinations — has been confirmed with an infestation of giant salvinia, a fast spreading invasive species.
The plant develops dense mats that shade out native aquatic species and reduce dissolved oxygen levels in water. Agricultural water use is impacted as salvinia obstructs intake pipes for irrigation. The dense mats hinder recreational fishing and boating. Twelve to 15 acres of the invasive plant have been detected on Lake Fork, the leading producer of trophy largemouth bass in Texas.
Giant salvinia is primarily spread from one lake to another by boat trailers. The principal ways to prevent the spread of salvinia (and zebra mussels) is for boaters to clean, drain and dry their boats and trailers before leaving a lake or stream. Transporting giant salvinia or zebra mussels is prohibited and punishable by a fine up to $500.
The Lake Fork Sportsman’s Association is hosting a public meeting with TPWD staff at 6 p.m. Tuesday, Nov. 21, at the Emory City Center.
