Video recorded June 14 by Terrence McKelvy showed the dead fish floating in the water in a section of the stream that runs between Prospect Avenue and Benton Boulevard.

"Look at this," McKelvy says in the video, who was on a bike ride and stopped to record the footage when he noticed the dead fish. "These are all fish in Brush Creek. Look at these big carp."

"If you’re driving down Blue Parkway this morning, and you smell something weird, it’s because there are about, no exaggerating, about a million dead fish that have floated to the top," McKelvy adds in the video.
