Wanli Creek channel red alert continues; nationwide Indigenous-area monitoring remains active

04:28 update

Information time: October 21, 2026, 04:28. The Forestry and Nature Conservation Agency's latest Wanli Creek measurement is from 08:40 on October 20. The personnel administration page was updated at 04:14, and Taitung Airport's daily flight board at 03:10.

Official sources: Forestry and Nature Conservation Agency October 20 Wanli Creek update, Public Warning Platform, Central Weather Administration heavy-rain advisories, Central Weather Administration severe-thunderstorm messages, Water Resources Agency disaster information, Agency of Rural Development and Soil and Water Conservation alerts, Directorate-General of Personnel Administration closure information, Highway Bureau, and Taitung Airport daily flights.

Affected Indigenous areas and alert levels:

• Wanrong, Hualien—Wanli Creek: The latest official measurement, at 08:40 on October 20, recorded a water elevation of 1,085.97 metres and storage of about 5.1113 million cubic metres. The dam body remained intact, water continued to overflow steadily, and downstream effects were confined to the river channel. The Wanli Creek channel and Hualien County-designated warning zone remain at `barrier-lake / red`. Red applies only to the officially designated zone; it does not mean all of Wanrong Township or every settlement is under a red alert.
• Taitung–Lanyu air service: The 03:10 board lists all 14 scheduled sectors as on time for October 21. Status is `transport / monitoring`; this is not a delay, suspension or red alert.
• Other Indigenous areas: The Central Weather Administration lists no active heavy-rain advisory or severe-thunderstorm message. No threshold-level official change was found for level-one flooding, sudden river rise, slope-alert escalation, disaster-related road closure, evacuation, sheltering, work/class suspension, transport suspension, major agricultural loss or public-service interruption.

Nationwide regional assessment:

• North: No threshold-level official change was found for Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, Tai'an, or nearby plains Indigenous areas; monitoring continues.
• Central: No threshold-level official change was found for Heping, Ren'ai, Xinyi, or Alishan. Scheduled construction traffic controls are not classified as disaster-related road interruptions; monitoring continues.
• South: No threshold-level official change was found for Indigenous areas in mountainous Tainan, Kaohsiung, or Pingtung; monitoring continues.
• East: The Wanli Creek channel and Hualien County-designated warning zone remain red. All 14 scheduled 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 riverbed, embankment surroundings, or Hualien County-designated warning zone. Lanyu passengers should still confirm service before departure. Official real-time notices take precedence.
