Living in Chicago, the apparent water retention capital of the world, I am seeing these more and more as its becoming mandatory to detain thousands/millions of gallons of water if nary a shovel is put into the ground. I see these ponds at Flossmore, Olympia Fields, Merit Club, Butterfield, Medinah, Butler, Westmoreland, etc. None of them are horrific....but none look too great either IMO.
