KUCHING – The Sarawak Government has carried out cloud seeding operations in major dam catchment areas to safeguard water resources and ensure the stability of hydroelectric power generation.
The initiative, conducted between 11 and 12 May 2026, was a joint effort involving the National Disaster Management Agency (NADMA), the Malaysian Meteorological Department (MET), the Royal Malaysian Air Force (RMAF), and several state agencies.
The targeted sites included Batang Ai Dam in Lubok Antu, as well as Bakun and Murum Dams in Belaga. The RMAF Kuching Air Base served as the operations and flight coordination centre.
The measure was introduced to stimulate rainfall in critical catchment zones, thereby supporting dam water levels essential for electricity generation, raw water supply, and long-term sustainability.
Officials explained that the operation was designed to mitigate the risks posed by prolonged dry weather and climate phenomena such as El Niño and La Niña.
Aircraft flew at altitudes between 5,000 and 9,000 feet, dispersing hygroscopic materials, including industrial-grade salt, into suitable cloud formations.
Continuous monitoring through weather radar and atmospheric analysis ensured both the safety and effectiveness of the mission.
The Deputy Secretary to the Sarawak Government (Administration), who also serves as Deputy Chairman of the Sarawak State Disaster Management Committee (JPBS), coordinated the operation alongside agencies such as the Civil Aviation Authority of Malaysia (CAAM), the Sarawak Ministry of Utilities and Telecommunications, the Sarawak Security and Enforcement Unit (UKPS), the Malaysian Civil Defence Force (APM), Sarawak Energy Berhad, and Sarawak Water Sdn. Bhd.
Authorities emphasised that the operation reflects the government’s commitment to protecting water resources and ensuring energy security.
By strengthening preparedness through technological approaches and inter-agency collaboration, Sarawak aims to safeguard the wellbeing of its people and support regional development.
Cloud seeding has long been used in Malaysia as a weather modification technique to address water shortages and stabilise dam levels.
In Sarawak, where hydroelectric power plays a central role in energy supply, such interventions are considered vital to maintaining resilience against unpredictable weather patterns.
The government has assured residents that further measures will be taken to reinforce water security and energy stability.
Officials reiterated that proactive planning and collaboration remain key to ensuring Sarawak’s resources continue to meet the needs of its communities and industries.
