'Tarag', in Bengali, means a pond or a medium scale waterbody having approximately 200 ft. of depth. The same meaning is conveyed by the Hindi word 'Talab' or 'Talao'. In 1706 there were only 17 waterbodies in Calcutta which catered the needs of native population. After the British settled down in the City they dug up or renovated numerous tanks to serve the purpose of drinking water, most of which are not in existence today. Among the existing ones, Laldighi and Wellington Square are the notable. But other tanks were later filled up to build parks like Curzon Park, Allen Park, Shraddhanand Park and many more.
But it was neither always the British who dug up the tank nor the purpose of public usage for which the tanks were dug up. In early nineteenth century, a Varanasi born businessman and philanthropist MANOHAR DAS SHAH converted an idle land into a pond to provide a drinking place for the cows. Yes, he was an animal lover and the tank is still there and known as MANOHAR DAS TARAG.
