Wanli Creek river-zone red alert continues; Lanyu ferries suspended through October 23

04:25 update

Information time: October 22, 2026, 04:25. The latest official Wanli Creek measurement is from 08:50 on October 21, and Taitung Airport's daily flight board was updated at 02:15.

Official sources: Forestry and Nature Conservation Agency October 21 Wanli Creek update, Public Warning Platform, Central Weather Administration weather alerts, Central Weather Administration heavy-rain advisories, Water Resources Agency disaster information, Agency of Rural Development and Soil and Water Conservation alert list, Directorate-General of Personnel Administration closure information, Highway Bureau Typhoon Qiangbi road advisory, Maritime and Port Bureau Typhoon Qiangbi transport notice, and Taitung Airport daily flights.

Affected Indigenous areas and alert levels:

• Wanrong, Hualien—Wanli Creek: At 08:50 on October 21, water elevation was 1,086.00 metres and storage about 5.1170 million cubic metres. The dam remained intact, water continued to overflow steadily, and downstream effects were confined to the 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 is under a red alert.
• Taitung–Lanyu passenger ferry: The Maritime and Port Bureau states that the Lanyu route is suspended from October 21 through 23. October 22 status is `transport / suspended`; this is a maritime suspension, not a red alert.
• Taitung–Lanyu air service: The 02:15 board lists all 14 scheduled sectors for October 22 as currently on time under `transport / monitoring`. October 21 cancellation records were not carried forward.
• Other Indigenous areas: The Central Weather Administration currently lists no active heavy-rain advisory. The rural soil-and-water authority reports zero red or yellow alerts for debris flow and large-scale landslide. No work/class suspension is listed. No new threshold-level official change was found for level-one flooding, evacuation, sheltering, Indigenous-area road interruption, major agricultural loss or public-service interruption.

Nationwide regional assessment:

• North: No threshold-level Indigenous-area change was found for Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, Tai'an or nearby plains Indigenous areas. The Tamjiang Bridge pedestrian/bicycle lane remains preventively closed, and motorcycle access may be closed after nightfall on October 22 depending on winds. This is a general-road `transport / watch`, not an Indigenous-area red alert.
• Central: No threshold-level change was found for Heping, Ren'ai, Xinyi or Alishan; monitoring continues.
• South: No threshold-level change was found for Indigenous areas in mountainous Tainan, Kaohsiung or Pingtung; monitoring continues.
• East: The Wanli Creek channel and county-designated warning zone remain red. Fugang–Lanyu passenger ferry service remains transport / suspended, while Lanyu air service is transport / monitoring. No new threshold-level 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. On October 22–23, Lanyu passengers should not proceed to Fugang Harbor without confirmation; air passengers should recheck flights before departure. Northern road users should follow the latest Tamjiang Bridge controls. Official real-time notices take precedence.
