Flow regime and periphyton cover estimates were made qualitatively and are presented in Figs. 17 and 18. Rockface units (Figs. 17,18) that either were dry or dominated by vascular plant vegetation were not used in these analyses. Statistical analyses were performed on log (x+1) transformed Springsnail densities.
