Hualien Wanli Creek Landslide-Dammed Lake Yellow Alert Lifted; Enhanced Level 3 Monitoring Begins June 29

# Hualien Wanli Creek Landslide-Dammed Lake Yellow Alert Lifted; Enhanced Level 3 Monitoring Begins June 29

20:01 Update | Yellow Alert Lifted, Still Maintaining 10-Day Breach Risk Reminder

Data timestamp: June 29, 2026 at 20:01. Hualien County government announced on June 29 at 16:34 that the Wanli Creek landslide-dammed lake yellow alert has been lifted due to revised rainfall forecasts from the Central Weather Administration not meeting alert thresholds; the county disaster response center downgraded from Level 2 activation to enhanced Level 3 activation.

This lift is specifically a "landslide-dammed lake yellow alert lift," not an adjustment of debris flow or large-scale collapse red/yellow alerts. Hualien County government still warns that a breach risk remains within 10 days; people should avoid entering river zones and alert areas unless necessary. According to the county government's announcement, the Forestry and Nature Conservation Agency monitored reservoir volume at 2.5942 million cubic meters (approximately 61.7%); subsequent monitoring must follow water level gauges, rainfall forecasts, and real-time notifications from central/local disaster response units.

The Directorate-General of Personnel Administration page on June 29 at 19:49 shows no school or office closures across Taiwan. The Agency of Rural Development and Soil and Water Conservation's debris flow and large-scale collapse disaster information network reports zero red/yellow alerts for this round; the Central Weather Administration alert special report pages show no expansion of torrential rain or heavy rain warnings to Indigenous townships. The earlier 07:58 Level 1 flood observation from June 29 is retained as a record from the Water Resources Agency disaster information network at that time; evening real-time flood alerts remain subject to the Water Resources Agency and local government announcements.

07:58 Update | Hualien Yellow Alert Maintained, Taoyuan and Tainan Low-Lying Areas Listed for Flood Level-1 Observation

Data timestamp: June 29, 2026 at 07:58. The Directorate-General of Personnel Administration's natural disaster school/office closure status still shows "no closures," so the June 28 school/office closures in Wanrong Village and Mingli Village (Wanrong Township) and Senrong, Changqiao, Shanxing, and Fengxin neighborhoods (Fenglin Town) have become historical records; they are not active on June 29.

The Hualien Wanli Creek landslide-dammed lake remains listed as yellow alert by the Hualien County government and the Forestry and Nature Conservation Agency's Hualien branch office at 17:00 on June 28: monitored water level elevation 1,066.63 meters, reservoir volume 2.3711 million cubic meters (approximately 56% of total capacity). After yellow alert, adjustments depend on water gauge readings, Central Weather Administration rainfall forecasts, and notifications from central/local disaster response units. This is a landslide-dammed lake yellow alert, not a debris flow or large-scale collapse yellow alert.

The Water Resources Agency disaster information network lists Level 1 flood alerts for Taoyuan City's Daxi District, Luzhu District, Longtan District, and Tainan City's Qigu District, Nan District, Annan District, and Anping District. Taoyuan Daxi and Longtan are adjacent to the Taoyuan Fuxing corridor; Tainan low-lying areas are listed for southern plain public service observation; these Level 1 flood alerts do not merge with the Hualien Wanli Creek landslide-dammed lake yellow alert zone and must not be mislabeled as debris flow or large-scale collapse red/yellow alerts.

00:28 Update | June 29 No School/Office Closures Across Taiwan, Yellow Alert and Public Service Status Separately Marked

Data timestamp: June 29, 2026 at 00:28. The Directorate-General of Personnel Administration's latest page shows that for the year 115 (2026), June 29 natural disaster school/office closure status is "no closures." Therefore, the June 28 school/office closures in Wanrong Village and Mingli Village (Wanrong Township) and Senrong, Changqiao, Shanxing, and Fengxin neighborhoods (Fenglin Town) have become historical records; they are not active on June 29.

The Hualien Wanli Creek landslide-dammed lake remains listed as yellow alert by the Hualien County government and the Forestry and Nature Conservation Agency's Hualien branch office at 17:00 on June 28: monitored water level elevation 1,066.63 meters, reservoir volume 2.3711 million cubic meters (approximately 56% of total capacity). After yellow alert, adjustments depend on water gauge readings, Central Weather Administration rainfall forecasts, and notifications from central/local disaster response units. This is a landslide-dammed lake yellow alert, not a debris flow or large-scale collapse yellow alert.

Recommended Actions

1. Residents of Wanrong, Fenglin, and the Wanli Creek, Matai'an Creek areas should follow real-time notifications from local offices, village heads, police/fire departments, Hualien County government, and central disaster response units; people should avoid entering river zones, stream beds, and former alert areas unless necessary.

2. Road users may travel on bridges opened per Hualien County government and Highway Bureau announcements but should avoid lingering near bridges, stream beds, and riverbanks; in mountain Indigenous townships encountering short-duration heavy rain, consult road authorities and local government announcements first.

3. School, public service, railway, and road traffic information should be based on real-time notifications from the Directorate-General of Personnel Administration, Hualien County government, local offices, education and transportation authorities.

4. As of this compilation, the Agency of Rural Development and Soil and Water Conservation's debris flow and large-scale collapse red/yellow alert statistics show zero; after lifting the Wanli Creek landslide-dammed lake yellow alert, it remains a landslide-dammed lake and downstream stream monitoring issue; do not mislabel as a debris flow yellow or red alert.
