At Point Calimere, Kodikkarrai, this is the only fresh water swamp. Water that gets collected by the rains.
Point Calimere swamps are part of the Great Vedaranyam Swamp.

Sweet swamp.
This picture was taken from a watch tower.

We saw Mongolian plovers (Charadris mongolus) on the other side.

Wading in the sweet waters!!!
nice shots!
