Not in Pennsylvania.

Yes it is lost. The Brook Trout fishing that we have today in this state is a mere shadow of what it once was.
I don't think there are many streams where a 12" brookie is more common than a 3" one - that implies some sort of weird occurrence where all the YOY have died off, as a population curve would tend to be clustered between 1-2 year old fish and tail off from there.
But, I think it is correct to say that there are streams in PA where 12" brookies are not uncommon. Many streams may have the curve fall off at 8-9" fish, but some have the habitat or some other combination of factors that allow fish to grow to 12" or larger. I agree with Chaz that some of those streams are in SE PA, but I've caught 12" or larger brookies in all areas of the state, except the NE and SW, both regions where I've never really fished a stream that has brookies in it.
While the angling literature mentions the migration of brook trout in pre-logging days, I'm somewhat skeptical of the claims of large quantities of large trout moving out of the bigger loctic systems. Under Behnke's classification of brook trout, our fish fall under the category of " a smaller generalist form that evolved in the small lakes, ponds, rivers, and streams throughout most of the original native range. This generalist form rarely attains sizes larger than 12 in (30 cm) or lives for more than three years." This does not preclude larger brookies from existing or being caught, but puts the tail end of the curve closer to 12" than 18".
I have no doubt that brook trout moved in and out of larger systems but some of the reading I've done suggests that streams like Kettle, Pine and the Loyalsock have always been the realm of the black bass in summer, even before logging. Anglers tend to tell stories (particularly those interested in selling copies of newspapers their articles are published in), so I'm still searching for late 18th or early 19th century scientific literature that documents (more than an anecdotal recollection) scores of 18" brook trout in PA.
