PETALING JAYA: Hot as it is, the rain still pours and dams serving even highly populated states are at satisfactory and sufficient levels.
But authorities in states like Penang and Johor still caution the population as a few dams there are below satisfactory levels, no thanks to the erratic La Nina (Little Sister) weather phenomenon.
The National Water Service Commission (SPAN) said that as of yesterday, all dams in Selangor, Perlis, Kedah and Melaka recorded levels of above 90%.
But four dams recorded water level less than satisfactory: Ayer Itam (47.4%) and Teluk Bahang (45.5%) in Penang, and Lebam (62.06%) and Semborong Barat (41.56%) in Johor.
SPAN corporate communication and consumer affairs director Mohd Fazil Ismail said water operators in all states had been asked to monitor the water level of the dams and rivers daily.
“This is to ensure that early action can be taken to deal with any possible disruption of water supply in the future.
“Currently, most of the main water treatment plants have an alternative source of water supply, which is through the Sungai Water Bank Reservoir that stores excess water during high water flow and is used when the river water flow is low,” he said.
Mohd Fazil advised users to be prudent with their water usage, adding: “Avoid wastage so that available water sources will last longer.”
Checks on Environment and Water Ministry’s web portal, publicinfobanjir, showed that dams in a few states were above the normal range and even nearing the alert level.
The Ulu Kinta Dam in Perak, for example, recorded a reading of 245.19m as of 4.15pm yesterday, nearing the 245.30m alert level. The normal level for this dam is 240m.
Others included the Klang Dam, which was at 95.29m as of 4.15pm yesterday, with the high alert level kicking in at 96.5m.
But dry weather is coming.
Malaysian Meteorological Department (MetMalaysia) director-general Muhammad Helmi Abdullah said the country was expected to experience less rainfall compared to other months until September.
The average temperature nationwide is between 32°C and 34°C but in some places, the maximum temperature can reach 36°C.
“The current temperature is normal. This situation is normal. It does not rain for several days in some places, so the surface of the earth will become dry and the temperature will rise,” he said yesterday.
Muhammad Helmi said climate change as a result of global warming increased the potential for extreme or erratic weather not only in Malaysia but throughout the world.
He added that small-scale extreme weather was difficult to predict due to its short duration and localised nature.
There was also no technology or modelling capable of predicting such extreme weather events, he said.
