I don't know how familiar you are with the NF in the article and WV in general but I'll give you a little insight.
In the mid 90's the NF was highly affected by AMD but beginning to clean up. A lot of places in WV are and we have our share of AMD impacted waterways. As they clean up and the PH is still low, brook trout will be one of the first fish to reappear, likely from out of the tributaries that were clean. If left alone, Brook trout will once again inhabit the mainstem and the tributaries. The main difference is that when a AMD impacted waterway is cleaned up in PA, the green light to stock the crap out of it and make "recreational opportunities"is given.
Brook trout numbers become suppressed and eventually brown trout begin to reproduce and take over a watershed. The PFBC is about to stock one such watershed I believe this year and has given a sportsman's club the ok for years.
It's ridiculous.
It has happened time and again in PA. I can think of many watersheds in my lifetime that had good size brook trout lost, some that are in process of being lost and ones still needing cleaned up that this will also happen to.
Truth is, if left alone, where competition is low, brook trout can grow quite large. This has been discussed on the forum many times.
WV won't be immune to this, if they aren't wise.
