I agree with Maurice regarding the "be careful what you wish for element" in the removal of Class B's on or largely on private land. His analysis is dead on, at least in my region, and probably in many others. Fortunately, for him and those who agree with him, I have said the same thing in-house, representing that viewpoint. Unstocked, wild trout streams are largely out of sight out of mind with respect to negotiations with landowners to keep them open to public fishing. This is why a single preseason and/ or inseason, low density stocking of easily caught rainbows or brooks is enough to keep them open to public fishing, but because these species are easily harvested their quick removal is perceived by many anglers and they move on to greener pastures as a result. This keeps stocked trout anglers happy, helps keep streams open to fishing, and minimizes impacts on wild trout populations to the extent possible under a stocking scenario.
Shifting to rainbow trout and reducing the stocking rate and frequency appeared to be the reason why a formerly stocked Codorus Creek section went from Class D or C to Class A. It did not work on Cold Run, Schuylkill Co, but we're attempting to duplicate the Codorus result on Leibs Ck in York Co.
