What is the current status of the Chajiaoliao Creek barrier lake?

A landslide blocked the river, forming a lake, but it is now naturally overflowing with stable water levels.

Is there a risk of the barrier lake collapsing?

The risk of another large collapse is low; even if it bursts, downstream water would rise about 70cm, within manageable limits.

What monitoring and response measures are in place?

24/7 surveillance cameras, drone surveys, water level monitoring, and on-site patrols are ongoing.

Are there any impacts on nearby residents?

There are currently no protected households downstream, and the Ruilong Waterfall bridge is unaffected.

Who is managing this situation?

The Rural Water Conservation Agency and Nantou County Government are collaborating on monitoring and response.
