General Measurements of ecological patterns are often used as primary biological indicators of river health. However, these patterns provide little information about important stream ecosystem processes (eg the sources and fate of energy and nutrients). The direct measurement of these processes is considered fundamental to the determination of the health of the stream and river ecosystems. Gross Primary productivity and respiration provide measures of the amounts of organic carbon produced and consumed within a creek system and thus provide a general indicator stream metabolism.
