Fish consumption advisories
A fish consumption advisory is in effect for Blue Ridge Reservoir because of mercury contamination. The state of Georgia advises people not to eat more than one meal a week of channel catfish greater than 16 inches long or white bass or largemouth bass between 12 and 16 inches long from Blue Ridge.
TVA collected channel catfish and largemouth bass from the reservoir for tissue analysis in fall 2005. The results, which were similar to those of previous years, will be provided to state agencies in Georgia. TVA will analyze fish from Blue Ridge again in the autumn of 2009.
