Contains S1-S5 Tables with individual table captions as follows.

S1 Table. Stream habitat metrics that were used as response variables in multivariate and univariate statistical models and tests. Metrics are grouped into different categories (bold italic headings). Metric names are those used in the manuscript text; abbreviations in parentheses are used in tables and figures. S2 Table. Minimum size thresholds for wood pieces to be considered “key wood”. CBW- Channel Bed Width.S3 Table. Best-supported models for each variable. Refer to Tables 1 and 2 for variable abbreviations. “TF” specifies whether response variable was natural log transformed (LN) or not (“No”). N is the sample size of available surveys used in that model. MR² is the marginal pseudo R² representing the amount of variance explained by fixed variables and CR² and the conditional pseudo R² representing the amount of variance explained by the fixed and conditional variables. See S1 Table and Table 1 for variable abbreviation explanations. S4 Table. Descriptions of channel process group classes. S5 Table. Multi Response Permutation Procedure (MRPP) pairwise comparisons for three management classes and two process groups. A is the effect size and P is the p- value for the test. The significance threshold was adjusted for multiple comparisons using Bonferroni correction 0.05/4 tests = 0.013.
