A local treasure will be featured on a national channel. Caddo Lake airs on National Geographic Explorer Monday, January 28 at 5 p.m.  Caddo Lake is a “Wetland of International Importance,” but has been threatened by the world’s worst invasive weed, Giant Salvinia. That drew the attention of National Geographic host, Sal Masekala, and producer J.J. Kelley. Both have traveled around the world, and yet found Caddo to be “one of the most magical locations” they had ever seen. 

East Texas and Ark-La-Tex locals will appear to discuss their efforts to manage Salvinia. These include Billy Carter, owner of Johnson’s Marina, the oldest inland marina in Texas; Daren Horton, President of the Caddo Biocontrol Alliance; and Laura-Ashley Overdyke, the Executive Director of the nonprofit, Caddo Lake Institute.  

Salvinia threatens many lakes in Louisiana, and a few in Texas. Great progress has been made in using weevils, along with aquatic herbicide, to fight this devastating plant. A grass roots effort was started to build the world’s first high production, climate controlled weevil greenhouse on the shores of Caddo Lake. Nonprofits and locals partner with Texas Parks and Wildlife and Louisiana Department of Wildlife and Fisheries to manage the floating fern.  

“Lake Eating Monster” airs as part of the one hour Explorer titled “Yellowstone Wolves,” on the National Geographic Channel, Monday, January 28 at 5 p.m (check local listings).
