FOR the third consecutive year, the Teluk Bahang and Air Itam Dams on Penang Island have experienced a significant drop in water levels due to reduced rainfall during the first quarter of the year.
Penang Water Supply Corporation (PBAPP) chief executive officer Datuk K. Pathmanathan said that as of March 31, the water level at the Teluk Bahang dam was at 47.3%, down from 61.7% at the start of the year while the level at the Air Itam dam dropped to 55.7%, a decrease of 21%.
“PBAPP has been reducing the daily water release at the Teluk Bahang Dam to conserve the available supply, as rainfall in the catchment area has been much lower than usual,” Pathmanathan said.
As for the Air Itam dam, he said rainfall in the area had reached its lowest in eight years.
He said PBAPP was working to stabilise the dam’s water level through the implementation of the Air Itam Dam Action Plan 2025.
"PBAPP would continue to monitor the water levels at both dams and reduce the release of water as needed, while ensuring that daily water supply remains consistent," he said in a statement.
With the support of the state government, PBAPP plans to request assistance from the National Disaster Management Agency (Nadma) and the Royal Malaysian Air Force (RMAF) for cloud seeding operations over the dams’ catchment areas.
“We hope that Nadma and RMAF will respond before the Teluk Bahang dam’s water level falls below 40%, as this is an ideal period for cloud seeding due to favourable weather conditions between the monsoon seasons,” Pathmanathan said.
He also urged the 67,000 residents relying on water supply from these two dams to use it wisely.
The Teluk Bahang dam serves the areas of Teluk Bahang, Batu Ferringhi, Tanjung Bungah, and Tanjong Tokong, while the Air Itam dam supplies water to Air Itam, Farlim, and Paya Terubong. – April 2, 2025

In the long run, Penang island cannot depend purely on dams fed by rainfall on their strictly limited catchment areas.
ReplyDeleteBack in the 1980s, there were still old folks who remember the original Sg. Air Itam, which was just a minor river , barely more than a stream before the dam was built.
The volume of rainwater that the river's catchment basin accumulates is still the same - or less - that's basic physics.
It's not surprising every dry season, the Air Itam dam water level drops dangerously low.
would have been enough for Penangites in the early 60's but obviously inadequate for today's Penang
