People are still advised against eating fish from the Ogeechee River or swimming in its waters until further notice. Bulloch County Public Safety Director Ted Wynn, after a conference call with Environmental Protection Division and Department of Natural Resources officials Tuesday, said additional testing is needed before determination can be made as to why several fish were found dead at the U.S. 301 (Dover) and Ga. 24 (Oliver) landings last week. Initial tests on very small fish found dead have not divulged the reason for the fish kill, but further tests on tissue from larger fish are expected to reveal results by Thursday or Friday, Wynn said.
