Georgia Environmental Protection Division officials still say the cause of a recent fish kill in the Ogeechee River likely is drought conditions, but they have not clarified the difference between conditions upriver and downriver from a textiles plant suspected by some to have been a contributing factor. In a related development, the advisories against swimming and fishing in the river were lifted Wednesday, Bulloch County Public Safety Director Ted Wynn said. In a statement released Wednesday, EPD spokesman Kevin Chambers said, “The Georgia Environmental Protection Division (EPD) has concluded that drought-related conditions are the likely cause of a fish kill in east Georgia’s Ogeechee River, but an exact cause will never be known.”
