"What is reamrkable to me is that the brookies survived 100 years of degradation and are still there, that doesn't mean I think we should continue the onslought through another century by stocking and encouraging brown trout to populate the stream."
"There is nothing blocking movement of the rainbows in that stretch over the river, so in time the brookies WILL be driven out."
Fish the Upper Schuylkill, or look on Google earth: Mines and water treatment inputs... maybe they are the problem, not stocked trout?. I've never seen a brown or rainbow there, stockie or wild. Browns and rainbows are less tolerant of acidity than brookies, and brookies can barely handle the Upper Schuylkill. You may not see BT or RT on the Upper Schuylkill, but there are treatment systems for AMD and sewage. Thanks to Mike for the info on the ST!...
see below: rainbow trout "are very sensitive to water pH levels and do not do well in acidic conditions."
