Manages hydrilla and aquatic vegetation in Lake Austin

Hydrilla, an invasive underwater weed, has stopped spreading in Lake Austin. The state's September survey found 575 acres, the same as in June. On October 29, the city released 7,091 sterile grass carp near Jessica Hollis Park, Walsh Boat Ramp and Bull Creek. One batch of 1,000 went upstream at Bull Creek, where dense weed still blocks boats.
