Dried Kinta River

This is an uncommon scene of Kinta River. The barrier or rubber dam nearby Wisma Taiko is raised to limit the water flow & causing river bed exposed at downstream. Anyway, I don't see people carrying any work down there which need to temporary dry out the river. I guess someone may be clearing rubbish in the river further downstream. The barrier released about half an hour later & the river is back to normal.
