An addendum to yesterday’s blog entry about trout range in Georgia during the Ice Age

In the comments section of my post hypothesizing the extension of the brook trout’s range in Georgia during the Ice Age James Smith points out that this species requires highly oxygenated water as well as lower temperatures.

Philip Juras painted the above portrait of Anthony Shoals in the Broad River.  This looks like clear highly oxygenated water and potential trout habitat.  Shoals like this occur as far south as Augusta.

  1. James Robert Smith Says:

    Yep. That’s what they need. I would figure that during the Ice Age the water reaching that part of Georgia was likely less turgid than in modern times. But with things like hemlocks living farther south, the water may have been highly tinted with tannin. Hard to say.
