Kithagnur lake is the local lake in the context of ISE's neighbourhood. It is the friendly neighbourhood lake in a sense. It is thus the first opportunity for students to get active in environment preservation efforts. Kithagnur lake has been deteriorating in the past few years owing to unchecked effluent discharge. The students joined a locally effort of elected representatives, citizens and school staff in planting trees around the lake. This was done in a bid to beautify the lake and encourage more foot traffic to its vicinity.
