This paper aims at providing a solution for augmenting the runoff water from major lakes of Chennai and Thiruvallur district of Tamilnadu. Hence an attempt was made to save surplus water from Puzhal, Ayanambakkam, Koratur, Ambattur, and Retteri lakes have been proposed. To interlink Puzhal lake with Koratur lake alignment is considered as it passes through the road network, excluding built-up areas. Water quality analysis was also done with a minimum of three samples that were collected from

The linking of the lakes is proposed based on the water quality assessment of each lake. This study suggests an efficient/optimal route or canal for interlinking lakes in a GIS environment. The elevation differences, slope and dimensions of the canal, and the possible best location to link the lakes/tanks were obtained through the spatial data in the GIS. This helps in an effective and optimized management of the water supply for Chennai city.
