some streams do seem to have Tuscarora bedrock headwaters but higher buffering bedrock a little bit further down. for example the one named croyle... maybe they were surveyed up in the headwaters I'm not sure

that was funny posts at the exact same time... I see what you mean they were surveyed in the headwaters

I've fished Swift. That makes sense and mirrors my experience. I fished up to the confluence with that UNT where the road splits off the main stem and follows the UNT. I know I caught fish near the confluence with Bull Run but I forget if I caught any more from there up to the UNT. This was in 2012. It was low, clear, and in August. It was ok, but I haven't been back since.

interesting long-term Virginia study, the number of acid-rain affected streams suitable for ST reproduction has increased

(would be great to have long term study of ST streams in PA)_

also data for Northern Appalachia, including Western Pa, showing slow stream chemistry improvement from acid rain issues.

Thanks Bob. I think I've got a copy of the Kirby Study, I volunteered for it but the timing of the study period was in conflict with me traveling for work. One of the streams I was to go to was North Kill. I knew the result before the study took place for that stream.

speaking of wbte, if you look at the pH of streams in the WBTE study, they all had brookies and some had pH readings as low as 5.6-5.8.

there must be streams right on the "acidity margin" w/o brookies, that could see ST with slight acidity reductions from current levels. of course it still may take a while
