Game and Parks suspects the remaining fish population is small. Members of the public reported the die-off to Game and Parks August 16th. Game and Parks staff found large numbers of largemouth bass, bluegill, channel catfish, black crappie, saugeye, and black bullheads dead at the lake.
Officials blame dense algal blooms over the past several weeks, combined with slight wind and wave action, with dropping oxygen levels at Olive Creek. Only the top level of the lake contains enough oxygen to support fish life. Game and Parks Fisheries Outreach Program Manager Daryl Bauer says more fish might die due to the condition and the surviving fish may be stressed.
An evaluation of the fish kill and the remaining fish schools will be conducted later this year.
Olive Creek will likely be re-stocked next year.
