With respect to the large fish in the Codorus, they were always larger and more abundant outside of the special regulations water where there was better big fish habitat! This, by the way, is typical of many special reg areas with brown trout populations and, in fact, I just had a pm this week from a board contributor regarding another special reg stream that is often mentioned on this board where the situation is the same...the large fish are much more abundant outside of the special reg area where the big fish habitat is better. This despite the fact that it is well known in the angling community (bait anglers included) that the big fish are there It's the habitat fellow anglers, not the regs.
Mike knows the deal better than any one of us for the most part. To add to his statement above, no doubt all fish (even stockies..lol) will seek out the best habitat. The SR areas are generally too short of a stream section, typically a mile or two, to hold even most of the fish stocked in the SR, thus many will move out into the open regulation (ATW) water. Also SR sections are are chosen for suitable fish habitat, but access and parking considerations also weigh heavily in the equation, so the best fish holding areas of the stream are not necessarily in the SR section.
As far as fishing pressure, generally there's heavy angler pressure early in the season or after a stocking. This pressure decreases rapidly as many of the (easy) fish are caught and they spread out over the stream and harder to find. In addition the weather warms and other fish species are targeted by many anglers (also the freezer is full...lol).
After the crowds thin and fish move it's usually best to chose the best habitat on the stream with respect to flow, temp, cover, and depth, rather than just fishing the SR water because you assume more fish will be there because of C&R or DH regs. If you can find a section of stream off the beaten path, so much the better since most anglers don't stray more than few hundred yards from the parking area.
Another benefit is most times in open water the fish appreciate your offering of flies since they don't get pounded day after day with every fly pattern ever created like in most SR areas.
Finally, while most SRs are crowded with anglers, most the open water sections will be empty of anglers, but may be loaded with fish eager to bite on your flies.
