Register in advance or join the meeting

There has been a spike in the extent of hydrilla in Lake Austin since June 2025. Hydrilla is a nonnative, invasive plant. In February, it was covering approximately 592 acres, up from 456 acres in September.

When considering hydrilla, please keep in mind:

1. Aquatic vegetation, including hydrilla, can benefit fish and water quality
2. Hydrilla can grow so fast that it becomes a problem for the environment and our community.
3. Managing hydrilla is a complicated balancing act that takes time.
