I definitely like smeltslayers idea about rotating ice fishing every three years for salmon only on Mooseleukmeguntic, Richardson and Aziscohos to thin out the short overpopulated salmon but I seriously doubt you will ever see it happen, longstanding tradition of closed waters to ice fishing in Rangeley region would be hard to overcome.
You can thank the invasive species for the decline of the fisheries. Yellow perch,pickeral,white perch and now sm bass. My boy got a 28" 8.5 lb togue out of there a couple years ago. We just dont fish it enough be cause the togue taste like mud out of Porter. There are some big fish still in there just got to put your time in. Seen a couple 4 lb salmon, and a bunch of brood stock 4+ lb brookies in the last few years hold over very well.
