About Ennore Creek:

• It is a backwater located in Ennore, Chennai along the Coromandel Coast of the Bay of Bengal.
• 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 depth of the creek varies from 1 to 2 m and is shallow near the mouth.
• The north–south trending channels of the creek connect it with the Pulicat Lake to the north and to the distributaries of the Kosasthalaiyar River in the south.
