I went to Bagan Lalang on 21 December taking my kids for a bit of beach fun and a little fishing. I was disappointed with the water quality during high tide as it looked reddish or rusty. I noticed there were reddish sediment on the sand bed all over during low tide too. This didnt happen the last time i came here. My white shirt and my kids clothing also became stained. The fishing was so so with seven belukangs and three buntal landed and all released unharmed.
My thoughts on the quality of the water were either it was due to the red tide which is rare or the polution released from the oil palm estates through the Sungai Sepang Kecil. I dont think it is coming from the Sungai Sepang Besar as the water was green. Is this a common occurrence there and has been happening for so long? If that is the case it is sad as it spoils the beach and turns away visitors which the municipal tries so hard to bring. I dont think the pollution should be released to sea without proper treatment.
On contrary the Port Dickson beach is getting better with the quality of water improving. It was green and clear when i went there on 23 December, however the water near the sewer discharge pipes along the beach smells which means the authority needs to look seriously to treat the sewer before discharging the affluent to sea. I couldnt land any bulus on that day probably because of the smell but i saw plenty of yellow tail barracuda chasing the baitfish.
Were there few months back looking at the beach profile at that area from Sg Sepang Kecil-Sungai Sepang Besar. Noticed the colouration at Sg sepang kecil as you mnetioned which really destroying that unique flats and that GoldCoast resort being built.
I though it was polution on the river until i reach small canal that feeds Sg Sepang kecil and found that there are oily stuff thats feeds into the river. These oily stuff comes from the soils itself. I have no idea what is that. Surveyed Sepang Kecil to Sg Besar and documents the severe erosions at its bank.
And you’re right, Sg Sepang Besar is greenish. Heard that it was bad before they close those industries due to JE.
Back to Sepang Kecil- i have no idea what is that orange colouring agent that tanned the water.
Must be due to the rotten oil palm seeds or trunks in the soil which will slowly seeping through to the river. I am surprised that nobody make noise of this occurance which is normal in Malaysia i guess. People will react only when the problem reach an epic proportion or their rice bowl is affected, then the government officials will start to move their fat ass from their comfy chairs and start to investigate. Just imagine if this thing happens in Australia, it will become a big environmental issue.
I managed to get my copy of aerial images from JUPEM for this area. Images on 1995 and 1999 shows that erosion or some part of thsese coastline and accretion at some area is a long process, long before they built the Jimah power plant.
Unfortunately i can’t share those images since it’s confidential images and i signed for it and have to report for all these stock that i have every year back to them.
