Since the PPL-Talen split it's weirdly difficult to find first-party information on this area directly from Talen online, without visiting in person (and if there's another land manager working on their behalf they seem to be pretty silent too). But some of the land is managed more as a nature preserve (with public access) than as a park per se. 

ex https://susquehannagreenway.org/parks/susquehanna-riverlands/

I haven't been up this way recently so not sure what signage, maps, etc. may be available at trailhead. 

Either way, definitely an area where improvements can be made.
