the blueback trout are reminants of ancient waters found in the state of Maine, they used to be thick around the rangley area around the turn of the century and were in fact a staple food source for many locals as they spawned in the streams thick enough to be netted in fact they used to say they ran so thick that there was hardly any water left in the brooks. The brookies used to feed on them in these lakes and grew big on these bluebacks. In fact the downfall of the brook trout population in the rangley lake areas coinceded with the downfall of these ancient fish. I am almost positive that these ponds are closed to ice fishing as well
