This is a picture of a freshwater stream in Rhinebeck, New York, an upstate country area. This stream flows behind my house further down the hillside. The water that is flowing is naturally filtered and purified through the rocks. It is a main water source for the local deer, coyotes, foxes, rabbits, bears and many more animals. I had known the source was local, but I had not known exactly where. I remembered that in the summer I had come down to see this same stream. There was no water at the time and it was pretty dry. The day before this picture was taken, the snow had begun to finish completely melting. I have found that the water is runoff from the snow melt which is the main reason I can only see this stream in the winter. Some of the water is also flowing up from the underground. In this picture, the water flows through rocks and trap any debris such as leaves which will float. Most smaller rocks will sink to the bottom. When I tasted the water further down the stream, it tasted very cold and fresh. Similar to bottled water. My investigation concluded, where the source is and the natural filtering process, making it drinkable.
