A standardized nomenclature is presented that clarifies the differences among measures of stream power. It is advocated that the term stream power be used in a conceptual context only. The recommended terminology for the various measures of this general concept is total stream power for the power of an entire reach or stream, cross-sectional stream power for power per unit length, mean stream power for power per unit wetted area, and unit stream power for power per unit weight of water.
