Ducks love fresh water.Since they dirty it up pretty quickly,fresh water was needed in the pond to keep them healthy.Aware of it,Governor's Principal Secretary Santosh Kumar Satapathy,who had got a pond made inside Raj Bhawan,Ranchi,had ensured that the water from a nearby tank is pumped into it regularly so that it carries oxygen ridden fresh water to his domesticated ducks. No wonder why these ducks look nice and clean.
