Ennore creek: Ennore creek 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.  The zone is spread over an area of 4 km, and the creek covers an area of 2.25 km.  It is located 20 km north of the city centre and 2.6 km south of the Ennore Port, and the creek area stretches 3 km into the sea and 5 km along the coast.  The creek is nearly 400 m wide, elongated in northeast-southwest direction and merging with the backwater bodies.  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.  The northwestern part of the creek merges with the tidal flats.  The soil in the region is of loamy and alluvial types.  Most of the area consists of tracts of alluvial soil and the eastern region comprises beach dunes, tidal flats and creek.  The creek is oriented from west to east and opens into the Bay of Bengal to the east at Ennore.  The creek acts as an outlet for the excess water from the Poondi Reservoir.  The creek separates the town of Ennore from the Ennore Port located in the north and the Kattupalli Shipyard located further north.  The North Chennai Thermal Power Station is located at the north of the creek and the Ennore Thermal Power Station is located to the south.
