Hydrilla in Lake Austin under Control
AUSTIN—A vegetation survey of Lake Austin by the Texas Parks and Wildlife Department (TPWD) in September revealed that the exotic plant hydrilla was finally under control. The survey found no hydrilla. It also documented that 203 acres of aquatic vegetation habitat, mostly Eurasian watermilfoil (milfoil), was still present in the reservoir. In the June 2013 survey, there were 330 acres of hydrilla and 135 acres of milfoil. The successful control of hydrilla was a result of a science-based stocking plan of sterile Asian grass carp, which target hydrilla as their main food source.
