Several aspects of flow have been shown to be important determinants of biological community structure and function in streams, yet direct application of this approach to large rivers has been limited. Our results synthesize, simplify, and interpret the complex changes in flow occuring along the Missouri and lower Yellostone Rivers, and provide an objective grouping for future tests of how these changes may affect biological communities.
