TPWD Has Plan To Help Control Giant Salvinia Infestation
JASPER, Texas — Favorable winters and high water levels have contributed to the spread of Giant salvinia (Salvinia molesta) in Toledo Bend Reservoir, one of dozens of lakes affected by exotic aquatic water weeds statewide. Infestations once confined to the backs of a small number of creeks and bayous in both Texas and Louisiana have now spread throughout the reservoir. Giant salvinia is easily spread overland to new locations by boat trailers, propellers, or even the intakes of jet-skis. The possibility of giant salvinia reaching neighboring Sam Rayburn Reservoir by this fall is extremely high, considering the number of boaters and anglers that utilize both reservoirs.
