Following heavy rains, tree remains and other debris brought by raging waters of Gin River collect under the Dodangoda and Agaliya bridges hampering smooth flow of river water. Remaining ever alert to these developments, the Sri Lanka Navy often clears blockages beneath those bridges, to avert possible flood threat in low-lying areas.

Accordingly, a team of Navy divers and a group of Rapid Action Boat Squadron personnel attached to the Southern Naval Command were pressed into action to clear the blockages under the Dodangoda and Agaliya bridges, averting possible threat to life and property from flash floods.
