The kill was reported to the Mississippi Department of Environmental Quality on July 13, and MDWFP biologists were dispatched to investigate the following day.
The agency said the creek was almost dry for a six- and seven-mile stretch between Hollandale and Arcola.
Dead largemouth bass, crappie, catfish, and gizzard shad were found in this section.
Although low water flow was believed to be the culprit, the exact cause of fish kill has not been determined yet.
The public can notify the Mississippi Department of Environmental Quality of fish kills in public waters by calling 601.961.5701 or 800.222.6362.
