Lake Austin, a popular recreational spot in Central Texas, is grappling with a growing infestation of hydrilla, an invasive aquatic plant that threatens the lake’s ecosystem and usability. First detected in 1999, hydrilla has spread rapidly in recent years, forming dense mats that choke waterways, harm native plants, and disrupt activities like boating and fishing. The Texas Parks and Wildlife Department (TPWD) has been working with local partners, including the City of Austin, to manage the problem through measures like deploying grass carp to eat the plant and applying herbicides. However, these efforts have not fully contained the spread, prompting concerns from residents and lake users who have noticed a significant increase in hydrilla since 2023.
