(CNN) The Kentucky River is brimming with dead fish as the fallout continues from a fire at a Jim Beam bourbon warehouse.

The warehouse in Versailles, Kentucky caught fire Tuesday night with 45,000 barrels of whiskey inside, according to Jim Beam's parent company, Beam Suntory.

The fire is out and the cause has not been determined.

Footage from CNN affiliate WKYT showed dead fish floating down the river and piling up along its banks as officials monitored the scene and kept up efforts to minimize the environmental impact.

As the fire subsided, a containment system was set up at the warehouse to help prevent runoff from polluting waterways and nearby drinking water sources, John Mura, a spokesman for the Kentucky Energy and Environment Cabinet, said last week. Aeration devices were installed in Glenns Creek and the Kentucky River to reduce the number of dying fish.
