Ennore

The completely industrialized north region is governed by Athipattu village panchayat in Minjur revenue block.

The north region is administered by Ennore revenue village in Athipattu Town Panchayat of Ponneri taluk of Tiruvallur district.

Six revenue villages, namely Kathivakkam, Ennore, Puzhudhivakkam, Athipattu Pudunagar, Kattupalli and Kalanji are located around the Creek.

Ennore Creek, along with the Buckingham Canal and the rest of the Pulicat water system has vast importance for the environment and for the local fisher folk.

The ecologically sensitive ecosystem was home to large swamps of mangroves that not only ensured a sustainable regeneration of fish resources, but also help mitigate flooding in times of strong rainfall, high tides and cyclones.

Despite being protected under such regulations, the unplanned industrial development of this area over the last few decades have had devastating effects on the whole ecosystem, resulting in loss of ecology and livelihoods of the fishing communities.

The drastic reduction in the wetland area, and the depth of what remained has reduced the Creek's ability to evacuate floodwaters from Kosasthalaiyar, Puzhal surplus, Buckingham Canal and the Araniyar.

The resultant storm surge of more than 1 metre above the astronomic tide had reportedly inundated low-lying areas in the region.

But with its water carrying capacity vastly reduced, the Creek's ability to absorb storm shocks has also declined.

The groundwater rich basin has six well-fields – Minjur, Panjeti, Thamaraipakkam, Poondi, Kannagiper and Floodplains—that yields up to 100 mld water for Chennai during stressed times.

To combat it, the state has invested money and fresh water in constructing injection wells and tidal regulators.

The Creek maintains a salinity gradient, and prevents seawater from entering too deep into the hinterland through the rivers, streams and channels.

A study by the Aquaculture Foundation of India and three institutions including Anna University, found high concentrations of heavy metals in the water and marine organisms in and around Ennore creek due to pollution from industries and domestic sources.

Species such as flathead grey mullet, a widely eaten fish had levels that hovered close to dangerous limits.

Over the years, several commercially valuable fish – including tiger prawn, mud crab, striped crab, sand whiting, silver biddy, cat fish, mackerel, grey eel catfish, croaker and white prawn – have disappeared from the creek.

For PM 2.5 (Particulate Matter or dust less than 2.5 micrometers in size) the air pollution is up to 3.7 times higher than standards prescribed by the Ministry of Environment, Forests and Climate Change (MoEFCC).

Metropolitan Transport Corporation runs passenger buses to Ennore from other major parts of Chennai city.

Due to siltation the creek has become very shallow, which makes fishing more difficult.
