From what I saw of what passed for a creek, it only flowed during rain events. No pools. Rainfall in surrounding watershed seemed main source of water. Unlikely source of BH.
Now it could be that BH got in through bird feces & maybe feathers. Coons, turtles or crawfish are a possibility, too. There were maybe eight ponds in the development, cross contamination is very likely. Though I'd still question no CC at all in the survey of a shallow BOW.
I prefer LMB and BG to CC, but CC wouldn't have been a show stopper the way BH were. That was back when I didn't realize how much CC would compete with LMB. Also, the developer boasted about good crappie catches near a submerged tree, and I'm not a crappie fan. I don't even particularly like to eat them!
Shallowness turned out to be an issue, too. I did know, even then, that too much shallow water meant huge weed problems. Survey showed lots of water 3 feet deep or less, though I'd been told it was deeper.
My inferences are just that, inferences. But they are based on hard data, which is the best we can do. All I can say for sure is that the survey idea, which I got from PB, saved me from a terrible blunder!
