Taiwan monitors barrier lake as Typhoon Barway approaches

Taiwan's Ministry of Agriculture is closely monitoring a barrier lake formed by a landslide in Hualien County's Wanli River, as Typhoon Barway approaches. The lake currently holds approximately 2.65 million cubic meters of water, representing 52.02% of its total capacity of 5.1 million cubic meters.

Officials estimate that if current weather patterns persist, the lake will not overflow for about nine days, as the water level is still 16.35 meters below the potential spillover point. However, the recent formation of Typhoon Barway, a moderate typhoon expected to strengthen and potentially approach Taiwan's eastern waters next week, has heightened concerns.

In response to urgent irrigation needs from farmers in the Wanrong and Fenglin areas, the Ministry of Agriculture's Water Resources Agency has constructed a temporary diversion channel and opened the Lin Tian irrigation gate. This ensures water supply while machinery is kept on standby for emergency operations.

Authorities have reminded the Hualien County government and local townships to continue patrolling and restricting access to the Wanli Riverbed to prevent premature overflow and ensure public safety. All relevant units are on standby, continuously monitoring water levels and dam stability, and adjusting response measures to mitigate risks associated with the barrier lake.
