LAKE LBJ – On Oct. 24, LCRA plans to begin applying a state-approved aquatic herbicide to treat water hyacinth, an attractive but invasive plant that has been multiplying on Lake LBJ. The date was rescheduled from the initial date of Oct. 18. 

LCRA officials have worked with the Texas Parks and Wildlife Department (TWPD) on the plans to treat the plant. Water hyacinth, a floating plant with an attractive purple flower, can expand rapidly on the surface of a water body, creating a hazard for boating on the lake. The surface area occupied by the plant can double in size within two weeks.

In previous years, LCRA and TPWD have conducted herbicide applications for water hyacinth in a single cove near mid-lake across from the Nightengale Archaeological Center. Recently the plant has spread to nearly a dozen coves downstream of Kingsland near the Granite Shoals community, likely due to flooding earlier this year.

Lakeside residents who find water hyacinth growing near their property are advised to pull the plant and place it on a dock or other surface to dry before disposing of it. This will help limit the spread of the plant.

LCRA officials may again adjust the date of the application depending on weather conditions and other factors.
