ATHENS–The Texas Parks and Wildlife Department has confirmed the presence of giant salvinia in Chaney Branch on Lake Fork. The infestation appears to be confined to this branch and another small cove west of the dam and occupies an estimated 3.25 acres. Judging by the distribution and age of the plants, it is apparent it has been in place for several months. As is the case for other introductions in East Texas, the plants were most likely introduced to the lake by boat trailer.
