I enjoy planning trips to fish for trout. In the states that I have visited on wild trout excursions, most have been very difficult to find info on wild trout. You can often find stocking info, but little to no info on wild fish. Vermont was ok, as were the smokies, but VA, WV, NY, NH, and other eastern states lack much stream data.
I agree that the search for good streams is one of the most rewarding aspects of fishing, but when you only have a week to fish, and you’re trying to plan an itinerary, spending a few hours to hike to a pond/stream/river that you think “might” hold trout a pain. Don’t get me wrong, I’ve done it, and been rewarded and disappointed, but it can be frustrating.
Circling back to PA, the lists/stream maps make our lives so much easier. Planning a PA trip is totally different. My personal opinion is that more info is better. List all of the streams we can survey. If there are 2,000 class a’s, that’s great. Many occasional anglers don’t even know the list exists, or think that all wild fish are “dinks”. I’ve seen streams dropped off of the stocking list and classified as class a, and the pressure drops dramatically. Also, with the added protection wild trout/class a streams receive, to me it’s a no-brained to get them listed.
