There has been an advisory of mercury contamination ongoing for years on the SOUTH fork of the Holston River (the part that comes down from Ft. Patrick Henry Lake past Eastman Chemical and others) but the new advisory now includes the north fork of the river. Just think, the south fork advisory takes in the area where there is fantastic rainbow and brown trout fishing in an area about 3/4 to a mile below the dam. I think a record rainbow trout may have come from that area.
