I took a scouting trip up to Clark last Monday (Aug 20) to see what the high water may have done. WOW! I am not too familiar with the FFO section but stopped at what I was told is called the lower lot where I have fished once earlier this year. A little ways downstream from where you walk in was where quite a number of big trees had fallen into the stream years ago. I wasn't quite prepared for how all the downfall had been washed together. All the debris and downed trees were packed in tight for at least 50 yards along the stream! I had never been downstream further than that so I figured I would venture down past the next hard left that the stream took. More packed in downed trees and debris but this time it was about 70 yards deep along the stream with only 2 spots each about 20 feet wide that you could wet a line in! All along the water was stained (tannic) but relatively clear. I would attach photos but they don't give a good representation of what it really looked like as you couldn't see 50 yards along the creek, much less 70.
Next I went up to the parking lot at the Appalachian Trail to assess the damage. Water was just as stained and high for this time of year, of course. You could see where the water had been high enough to completely wash over that high point in the middle that the creek meanders around. Sand was deposited all over the place (same with my previous stop). I measured the water temp on the downstream side of the culvert and was surprised that it was 71+ degrees. I have never seen it that warm there because of letting the water from the bottom of the dam. Makes sense now if the water was coming over the top of the dam, as an earlier post stated. Hope the temps drop significantly soon so I can explore some more sections on Clark and fish at the same time.
