There’s a lake about 40 miles north of here that is also a flood control reservoir. There’s good fishing in the summer, then it’s drained down about 20 feet. A friend of mine happened to be looking for deer hunting spots a couple of days after the draw-down. Instead, he spent the afternoon walking around in what had been shallow water. He came home with a bucket of fishing lures and a fishing rod. He found an anchor, too, but he didn’t want to carry it back to his truck.
The one in Louisiana was called Lake Peigneur, if I recall correctly.
That’d sure throw you off, though - imagine getting up, having a nice stretch, looking out your window, and the lake is gone. I’m sure you would do a real, live double-take at that. “The lake is gone. I know it was there last night. Where could it be? Lakes don’t just…leave.”
Of course, your second thought would be, “Oh, shit! There goes our property value!” Can you see the realtor’s tour? “And if you look out the picture window, you can see the gaping muddy hole where the lake used to be…”
