I've thought for years that they should stock down there. That's not wild trout water, there's public access on state forest land, and it's scenic.
The apparent reason they didn't stock there are small mine drainage seeps on the west side, but I think those are diluted by the much larger flow of Kettle Creek so that the water quality is OK for early season put-and-take fishing. Shift the hatchery trout currently being stocked over native brook trout in many streams to places like that.
Another good possibility would be Sinnemahoning Creek. The water quality is fine. The only drawback is that a lot of the land along there is posted, but maybe they could work with some of the landowners to get access.
