In a recent article in the Marshall News Messenger titled "Before treating salvinia, residents must file paperwork", Tim Bister, Texas Parks and Wildlife Department's district supervisor and fisheries biologist in the Caddo Lake area discussed appropriate steps for homeowners and landowners around Caddo Lake to take if they want to fight giant salvinia on their own.
Caddo Lake is a public water body and as such, is managed by the state. To deal with nuisance or invasive aquatic vegetation like that commonly present at Caddo Lake, the state requires that a document known as an Aquatic Vegetation Treatment proposal be filled out. What these documents do is outline the type of aquatic vegetation (floating, emergent or
submerged), the target aquatic vegetation species name, the estimated
amount of aquatic vegetation acreage to be treated, and the proposed
treatment type (mechanical, biological or chemical). A map also accompanies these treatment proposals as well and helps TPWD ensure that there aren't any conflicting treatments planned.
While the article provides more specific information about Aquatic Vegetation Treatment proposals, it is always a good idea to contact the TPWD District office to discuss plans. In the Caddo Lake area, TPWD's District Office is located at 3802 East End Blvd. So., Marshall, Texas 75672. You can also contact them by phone at (903) 938-1007.
