I'll play devil's advocate on this (but not to diminish the severity of the problem) :

I'd like to know -

How many fish were tested
What species of fish were tested
Where those fish were taken from

Seems to me, considering the location of the power plant being so close to the dam ... and the water flow towards the dam ... that a lot of that "polluted" water should be localized.

And something else that may prove to be a problem, if in fact the polluted water IS being washed thru the dam, is that the Dix River trout population would be receiving as much or more chemical pollution as the area between the coal ash drainage & the dam.

And chemical pollution from the power plant is only one factor ... considering all the stuff that's dumped into the lake (from all parts of it), and the hundreds of old 55gal drums that have been sunk in that lake, containing who knows what. Remember ... originally, most docks were floated by 55gal drums, long before styrofoam blocks were used. And many of those were sunk, after getting loose from those docks, so as to not be a hazard to water traffic.
