Pool/glide/eddy quality

Rated based on the variety and spatial complexity of slow- or still-water habitat within the sample segment. It should be noted that even in high-gradient segments, functionally important slow-water habitat may exist in the form of larger eddies. Within a category, higher scores are assigned to segments which have undercut banks, woody debris or other types of cover for fish.

0 - 5Pool/glide/eddy habitat minimal, with max depth <0.2 m, or absent completely
6 - 10<10% pool/glide/eddy habitat, with shallows (<0.2 m) prevalent; slow water areas with little cover
11 - 1510-50% pool/glide/eddy habitat, with deep (>0.5 m) areas present; or >50% slow water with little cover
16 - 20>50% pool/glide/eddy habitat; both deep (>.5 m)/shallows (<.2 m) present; complex cover/&/or depth >1.5 m
