Streams are an important part of the landscape. Streams transport water, sediment and energy; provide habitat for aquatic life and support terrestrial life; provide a place for recreation; and in many cases serve as a water supply. The health of streams—or their ability to perform these important functions—is dependent on the conditions of the watersheds which they drain. Changes in land use within a watershed can affect a stream’s health (Figure 1).
