Ennore Creek

It is located in the zone comprising lagoons with salt marshes and backwaters, submerged under water during high tide and forming an arm of the sea with the opening to the Bay of Bengal at the creek.

Once a flourishing mangrove swamp, the creek has been degraded to patches in the fringes mainly due to human activities in the region.

The north–south trending channels of the creek connect it with the Pulicat Lake to the north and with the distributaries of the Kosasthalaiyar River in the south.

Most of the area consists of tracts of alluvial soil and the eastern region comprises beach dunes, tidal flats and creek.

As per the 1991 Coastal Regulation Zone notification, the entire Pulicat water system is designated CRZ I.

[5] Both the rivers do not reach the sea directly but confluence in the brackish water bodies, mangroves situated at the fringes of the creek and the Buckingham Canal.

Studies reveal that permitted discharges account for less than 40% of the total BOD load measured in the creek.
