There have been several reports concerning dead fish that have been found along Delaware Lake.
Officials have now provided an explanation as to why they are dying.
A photo was taken earlier on Monday, and the Ohio Department of Natural Resources said there is no need to worry about the water quality being a cause for the fish kill.
It is not unusual for the fish, which are called Gizzard Shad, to die when the water temperature quickly changes from cold to warm.
The ODNR says that not all the fish die, but many of them do during this time of year.
