“Korattur Lake”的意思、由来-开放百科全书

Korattur Aeri, or Korattur Lake, is a lake spread over 990 acres in Korattur, Chennai, India. It is located to the north of the Chennai—Arakkonam railway line. It is one of the largest lakes in the western part of the city.

Korattur Aeri is one of a chain of three water bodies, including the Ambattur Aeri and the Madhavaram Aeri, where surplus water from one is transported to another. The water from the lake had been supplied to Chennai residents for a brief period when there was a shortage in the late 1970s. However, over the years, the lake has been contaminated with sewage and industrial effluents from surrounding areas such as Pattaravakkam, Athipet and Ambattur.^[1]

Developments

In 2013, the Water Resources Department decided to rejuvenate and beautify the lakes in Ambattur, Madhavaram and Korattur with parks and walkways.^[1] The total project costs {{INR}} 600 million.^[2] In 2018, the corporation identified and removed about 550 encroachments along the bank of the lake and the bund will be strengthened to a distance of 3 kilometers.^[3]
