From NBC 4:
Something stinks -- and the source of the smell could lie beneath murky waters here in the Springfield Gardens section of Queens where residents have had enough of the odor.
It's a problem that has many of the folks in the neighborhood fishing around for answers after spotting a large number of dead fish inside the waters here at Springfield Park.
Some are citing the heat as a possible reason. But Parks believes there's a lot more to it.
"We're trying to figure out what's going on," said Parks. "Did somebody spill something there? Is there a leak under the lake? But we can't get any answers from 311."
So, we put in a phone call to the New York City Parks department and quickly learned that officials there are aware of the problem and "have sent some of the fish to the Department of Environmental Conservation for testing to find out why and how they died."
