Haven't fished Commonwealth in many, many years. I grew up in one of the houses backing up to the park. Back when, they didn't stock it with trout, or anything else. There was illegal plantings of all kinds of stuff. We used to catch carp by the dozens, and when the crappie came into the rocky edges to spawn, we'd catch literally hundreds in a couple of hours -- a few big ones. And an occasional bullhead cat, sometimes large. And as kids, we always figured it was some massive bullhead we'd be hooking when we dunked a worm in the deepest part of the lake, which we never saw, and took full spools of line -- we figured it was bullheads, until we saw someone catch a sturgeon (using much heavier gear than we ever did).
I think the "restoration" (it was a swamp 50-60 years ago, some developer dug out the lake to OFFer "lakefront" houses, which used to flood like crazy... not sure what they're "restoring" it to) messed it up. But if I still lived there, I'm sure I'd be fishing it often.
Commonwealth was where I learned to fish, and learned to love fishing.
