As a long time resident of the Central Florida - Orlando area, I give you beautiful Lake Apopka.
Ah, once beautiful. It was the bass fishing capital of the South. Large clean lake, the tastiest bass you could ever catch. A virtual paradise before Disney.
Then WW2 happened, the top third of the lake was drained for war-time farming. Then the land was given over to the farmers, who loved their pesticides and fertilizers. All that flushed into the lake, freely and without restriction.
The fish, and everything else that depended on the fish, like the birds and the lake's fisherman, all died out. The lake turned into a huge sewer, almost completely bereft of any hint of life. On a hot August day, residents said you could smell the lake from downtown Orlando.
In the last twenty years, we've slowly brought the lake out of its catatonia, and life is starting to return. Birds have come again (at least two times, the birds were killed by the lake's poisonous muck), and there are fish, not bass, and not edible.
But to celebrate Lake Apopka becoming possibly beautiful and fishable, there's a nice proposal to build a large airport very near it. That won't scare the birds, we're advised.
