Euclidean Sum of Squares was used to calculate the amount of stream reach dissimilarity within and between 3 prominent eastern Oklahoma ecoregions : Boston Mountains, Ozark Highlands, and Ouachita Mountains. Dissimilarity proximity coefficients were used to cluster stream reaches and create exemplars for each cluster. Streams were classified using the Rosgen classification to evaluate whether dissimilarity values could be applied to the classification. Metrics used to calculate stream reach dissimilarity were median particle size, bankfull width, width–depth ratio, gradient, and sinuosity. Maximum stream reach dissimilarity between 2 sites within the same ecoregion is highest in the Ouachita Mountains and followed by the Ozark Highlands and Boston Mountains. Utilizing the dissimilarity of channel morphology for the purpose of regional classification helps in the understanding of how broad-scale processes influence the fluvial system
