The lake is "under siege" by a fast-spreading, Velcro-like aquatic fern, Salvinia molesta, also known as Giant Salvinia. Accidentally introduced to the lake by boaters, the noxious weed doubles in size every two to four days, rapidly killing off life below the surface. Most of the growth of the plant is on the Louisiana side.
The working principle is illustrated in for the Giant Salvinia. [4] The leaves of S. molesta are capable of keeping an air layer on its surfaces for a long time when submerged in water. If a leaf is pulled under water, the leaf surface shows a silvery shine. The distinctive feature of S. molesta lies in the long term
