Lake Fork Confirmed with Giant Salvinia

Contributed by John Jefferson


Texas Parks and Wildlife Department (TPWD) this morning released an announcement 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. Recreational fishing and boating is hindered by the dense mats. Twelve to 15 acres 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 way to prevent spread 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.
