Assessment j Excellent Excellent Excellent Poor Excellent NG
a. Small stream; unable to measure flow
b. Canopy cover: S=shaded; MS=mostly shaded; 50/50=50% shaded; MO=mostly open; O=open
c. Habitat assessment form: RR=riffle/run (Barbour et al. 1999); GP=glide/pool (Barbour et al. 1999)
d. Stream no longer existed
e. Not wadeable; No flow taken
f. No flow; did not collect samples, habitat assessment, or flow
g. No flow, standing pools only
h. No flow measured
i. Habitat assessment not conducted
j. NG=no assessment guidelines; for 68b, used guidelines from adjacent subecoregion 68d; limited reference data available for 68f; 68f guidelines calculated from combintion of reference data from 68f, and adjacent
subecoregions 65i, 67f, and 68e.
