Dead fish floating on the Ranchi Lake, commonly known as Bada Talab, are a common sight which has raised environmental concerns.
Locals say the fish are dying because of depleting water levels, while others believe that rising pollution levels is the reason.
The Jharkhand State Pollution Control Board (JSPCB) admits that the pollution levels have risen alarmingly. "We are worried. We have asked for the contaminated water samples," said S K Sinha, member secretary of JSPCB.
