premise: The water looked as if it had been drained from a swamp - brownish - green , with many varieties of plant life lining the surface . The only movement in the water came from the tiny water spiders and occasional minnows darting to the surface in search of food . It was very quiet and serene , and if I had n't known better I would ' ve thought I was in the Louisiana Bayou . It was just so hauntingly beautiful . Why did the water look this way ?
hypothesis: It was stagnant water that had been there a while with no flow .
