Delhi’s artificial Sanjay Lake recently turned into a graveyard. Hundreds of small Gambusia or mosquitofish, along with larger tilapia- or carp-like freshwater species floated to the surface of the stagnant water, making the overall scene resemble straight out of a horror movie. 

Hundreds of dead fish floated belly up on the stagnant water of the lake.

Sanjay Lake is located in East Delhi’s Trilokpuri and spreads across nearly 187 acres. It is maintained by the Delhi Development Authority and is also a notified protected forest under the Delhi forest department, according to an Indian Express report.

According to environmentalists, a host of factors, including human negligence could be responsible for the fish kill.

Environmentalists told the newspaper that the ghastly scenes at Sanjay Lake could be a result of a combination of factors: high temperatures due to the ongoing searing heatwave in the city; the high chemical load in the water body and the lack of replenishment of the lake’s water, which could have helped flush out toxins.
