Stream is a body of running water moving over the earth’s surface in a channel or bed, such as a creek, rivulet or river that flows at least part of the year. Streams are dynamic in nature and their structure is maintained through build up and loss of sediment. Streams are typically formed by natural forces but also includes drainageways, outside of street right-of-way, which were formed by man in the past. Storm sewer systems and roadside ditches in street right-of-way are not considered streams.
