On August 2, 2025, authorities reported that a semi-permanent big bag barrier wall in the Koh Saai community of Mae Sai District, Chiang Rai Province, designed to protect the area from river overflow during the rainy season, has suffered structural damage. A 10-meter section of the barrier on the Tha Khee Lek side, opposite the Koh Saai community, has collapsed from water pressure, causing concern among local residents. Officials are expected to accelerate repairs to prevent flooding during the ongoing monsoon season.
Meanwhile, heavy rainfall since 7 p.m. in Muang District, Chiang Rai Province, caused water from Doi Lik Khao to overflow, flooding one lane of Phaholyothin Road near the Mae Phu Ka community entrance. Disaster prevention officials and Ban Du police set up warning lights to prevent accidents. By approximately 9 p.m., rainfall had decreased significantly and water levels had dropped noticeably, with normal traffic conditions expected to resume shortly.
