Analyses of stream link lengths drawn from drainage networks defined by Strahler order or by magnitude have generally failed to reveal any evidence of organization or covariation between interior and exterior link lengths. Classifying networks by maximum source height or diameter reveals that link length organization is network scale dependent, may not appear significantly for small‐magnitude headwater systems, and is environmentally sensitive to spatial scale threshold constraints. Empirical analyses of networks from two contrasting geomorphic environments reveal that link length organization can be regionally discriminatory and can also differentiate between network states defined by blue lines and valley systems on 1:25,000 topographic sheets. Link lengths were derived by using an automatic digitizer, and these results constitute the largest data set of individual link length measurements reported to date.
