SEGAMAT - The area where eight boys were believed to have drowned along the Muar River is not far from a favourite recreational spot called Pasir Rusa.
The recreational area, which is almost next to the Buloh Kasap town centre, about 8km from here, is well kept and has an eatery.
It is also where people living in the area bring their children for picnics or for some fresh air as the river running alongside is not very deep.
The river in the area also has a sloping bank where visitors sometimes take a dip.
However, at the spot where the boys drowned, about 50m from the recreational park, the water is very deep and the riverbank falls sharply without any slope.
Locals believe that sand extracting activity in the area had created an area where the river bed is much deeper compared to other parts of the river.
A man, who was at the scene during the search and rescue mission, claimed the sand extracting activity had created a "deep hole" in the river.
