The Ministry of Environment and Forests, Government of India, New Delhi has sanctioned Projects for revival  of Ooty and Kodaikanal Lakes under National Lake Conservation Plan with 100% financial assistance.  Environmental upgradation by bioremediation of Ooty Lake has been taken up and completed by Tamil Nadu water Supply and Drainage Board and PWD during 2005.

Though the remediation was successful, in view of the continued letting of sewage water in the intervening period, the quality of water has once again deteriorated and is not up to the standard now. On seeing reports about the deterioration of the quality of water in this lake as well as in some other water bodies, Hon’ble Chief Minister directed that all the polluted water bodies especially the Ooty lake must be cleaned up immediately on a war footing and maintained without further pollution. As per the instruction of the Hon’ble Chief Minister detailed discussion were held with concerned departments and it was proposed to implement a detailed action plan with multi sectoral approach to clean up and revive the lake on a permanent basis. Under EPRED fund a sum of Rs.4.27 Crores has been sanctioned for carrying out  the following works to revive Ooty lake.
