Less than two feets of water. Clear water with just some gentle waves moving at the surface. Good sunlight of the mid-morning. I found very interesting the light paterns moving on the river bed. It reminds me some psychadelic art of the 70's. I was about to capture the piece of art when a crayfish entered the scene from the right. He walked a little, stop in front of me and made a big cloud of dirt that fell back on him to make him almost disapear. This is their stategy to avoid being eated by seagull.
