A watershed is the area of land that water flows over to reach a river, lake, or a stream. Near the upslope edges of a watershed, small tributary streams (1st, 2nd and 3rd order) begin gathering water that flows downstream into larger rivers and eventually drains into a river, bay, or ocean. Some of...
