Traditional waterbodies in Delhi: Need historical data to be compared with the present status

I am a research scholar from Delhi University working on the declining status of traditional waterbodies (ponds,lakes) in Delhi. And also the environmental impact of construction sites related to the Commonwealth games on water bodies of Delhi. I want to locate old records(historical data) of the traditional water bodies in Delhi which can be used as a comparison to the present status. Kindly suggest the right source to relevant data and information for this work.
