SAN ANTONIO (KTSA News) — The Guadalupe Blanco River Authority says it will be drawing down all of its lakes starting next month.

The district said engineers have determined a drawdown is the only viable option to minimize risks to aging dams.

The drawdown will begin September 16th.

The New Braunfels Herald-Zeitung says the lake to be drained will be Lake Gonzales — followed by Meadow Lake,Lake Placid and then Lake McQueeney.

The decision comes after a dam failure in May at Lake Dunlap.
