Could be. One pond is rain fed and the depth varies considerably. The result is the shallow-water vegetation takes a real beating and no doubt decomposes when left high and dry for too long. The other pond is always full and has a deep area that would not freeze anywhere near the bottom, but of course it is completely iced over. That pond is fed by ground water and surface drainage.
Larger lakes and ponds that are steam-fed probably have some water with a bit of oxygenation flowing in under the ice all winter. That could certainly make a difference.
I ice fish a small farm pond every few years. Some years it is full of nice 8" bluegills. Some years its completely dead. You drill a hole and a foul smell comes out of the water. What happens on this pond is that in extreme winters, it gets thick ice cover and heavy snowfall, there is no oxygen. The weeds die and rot and that fouls the water. In spring, the water is crystal clear and there are no fish. As the water gets oxygen after the ice melts, the weeds recover, the fish move back in from surrounding ponds through channels and the process starts over.
Perhaps the pond you're looking at has no good source of consistent oxygen, so any fish that would start in it never get to live past a year through winter. Your state biologist should be able to analyze it for free and give you suggestions on what is really going on, how to stock it, improve it, etc...
