For the depth/flow relationship, the mean of the inflection points for rimes, runs and pools was 0.5 ft, 1.2 ft, and 3.2 ft, respectively (Tables 5A-5B-5C). The inflection points for the stage/flow relationship were fairly similar between the three habitat types. The increase in stage (rise in water surface elevation from stage at one cfs) was 0.84 ft on rimes (92 cfs), 1.14 ft on runs (84 cfs) and 0.97 ft on pools (85 cfs) (Tables 5-A-B-C). The stage/flow relationship is related to stream width. Stage increases quicker in parts of the channel where stream width increases slower. Stage is an expression in water depth. In rimes, the stage of zero flow is the deepest part of the channel (thalweg) and therefore stage is equivalent to maximum depth. On runs and pools the stage of zero flow is dependent on a downstream control point. The inflection points for stage and average depth were very similar for the three habitat types, but stage was higher than average depth on rimes, stage and average depth was similar on runs, and stage was less than average depth on pools. Width/depth ratio can be a useful expression of habitat quality. High width/depth ratios result from wide/shallow habitats and river sections with high ratios are likely to have limited fish potential and are very likely to become passage barriers for larger fish. Riffles should have the highest width/depth values, and pools the lowest. The inflection points for the relationship between width/depth ratio and flow were at the lowest flows (79 cfs, 76 cfs, and 74 cfs) for the seven variables (Table 4: A-B-C). The means of the inflection points for width/depth ratio are 453, 195, and 57 for rimes, runs and pools respectively (Table 5: A-B-C). Width/depth ratio had the greatest coefficient of variation for the seven variables. Cross sectional area is width times depth. In contrast to width/depth ratio, cross sectional area is lowest on rimes, and highest in pools. Cross sectional area was the .. 23
