Spring Creek's management was also changed to wild trout management and catch-and-release by chemical contamination.
Before that, it was stocked with 19,000 trout per year, and the limit was 8 trout per day.
Very few people thought of it as a wild trout stream back then.
I've read some of the older writings about Spring Creek. For example there was a section on Spring Creek in a book called "100 Pennsylvania Trout Streams and How to Fish Them" which was published in around 1963.
The article was several pages long, and also included descriptions of Bald Eagle Creek.
There was no mention of either stream holding wild trout. It didn't say there weren't wild trout either.
There simply was no mention of wild trout. I think that it was simply not on peoples' radars back then. Which seems hard to fathom, because they must have caught juvenile wild trout, smaller than the Fish Commission stocked. And also saw brown trout spawning in the fall. How could they not have realized that there were wild trout in the streams?
