Wanli Creek river-zone red alert continues into October 18; nationwide Indigenous-area monitoring

04:07 update

Information time: October 18, 2026, 04:07. The latest official Wanli Creek status update was issued on October 16. The personnel administration page was updated at 03:55, and the Taitung Airport flight board was updated at 04:07.

Official sources: Forestry and Nature Conservation Agency's October 16 Wanli Creek update, Public Warning Platform, Central Weather Administration weather advisories, Water Resources Agency disaster information, Agency of Rural Development and Soil and Water Conservation alert list, Directorate-General of Personnel Administration work/class status, and Taitung Airport daily flights.

Affected Indigenous areas and alert levels:

• Wanrong, Hualien—Wanli Creek: The latest agency update reports a water elevation of 1,086.16 metres and storage of approximately 5.1462 million cubic metres. The dam remains intact, overflow is stable and downstream effects are confined to the channel, but storage continues to pose risk. The Wanli Creek channel and Hualien County-designated warning zone remain `barrier-lake / red`. Red applies only to the official river-zone boundary; it does not mean all of Wanrong Township or every settlement is red.
• Lanyu air transport: Taitung Airport's 04:07 board shows all 16 Taitung–Lanyu sectors scheduled for October 18 currently on time. Status is `transport / monitoring`; this is neither a suspension nor red.
• Other Indigenous areas: The Central Weather Administration county table lists no active weather advisory. The slope-hazard system lists zero red or yellow debris-flow alerts and zero red or yellow large-scale-landslide alerts. The personnel administration page updated at 03:55 lists no work/class suspension. No other threshold-level official change was found.

Nationwide assessment:

• North: No official threshold-level heavy-rain, thunderstorm, level-one flood, flash-rise, slope-alert escalation, road closure, evacuation, sheltering, work/class suspension, transport suspension, major agricultural-loss risk or public-service interruption was found for Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, Tai'an or lowland Indigenous areas; monitoring continues.
• Central: No such threshold-level official change was found for Heping, Ren'ai, Xinyi or Alishan; monitoring continues.
• South: No such threshold-level official change was found for Indigenous areas in mountainous Tainan, Kaohsiung or Pingtung; monitoring continues.
• East: The Wanli Creek channel and designated warning zone remain red. All 16 Taitung–Lanyu sectors are currently on time under transport / monitoring. No new threshold-level official change was found elsewhere in Yilan, Hualien or Taitung Indigenous areas.

Recommended action: Do not enter the Wanli Creek embankment area, riverbed or designated warning zone. Lanyu travellers should still confirm service before departure. Follow the latest official notices.
