I've forwarded this to Jeff for his fisheries review.
As for other organisms, if this was happening in a closed canopied mountain stream, I would say this thermal impact
could be deleterious to cold -water adapted invertebrates.
However, given the geographic location of this site, and the open nature of the canopy (i.e., plenty of sunlight), I would
expect the impact to be negligible for most invertebrates.
Of course, the extra thermal inputs from this facility could cause synergistic thermal impacts to some invertebrates if
average summer temperatures continue to climb as they have been.

Subject: Dan River Thermal Model
Eric,
Could you please take a look at the attached thermal model, it is only about 20 pages long with many illustrations.
I have only two questions:
1) Would this discharge prevent safe passage of fish through the thermal plume?
2) Do you expect any other negative impact on the aquatic organisms from this plume?
Thank you!
Sergei
