Points represent the weighted mean species scores for each reach. Waters of these reaches had slightly higher than average residue, specific conductivity, and hardness. Reaches in the Maple and Forest Rivers had much higher than average CV of mean monthly discharge and much lower than average annual and May low discharges. Figure 23 .

Points represent the weighted mean species scores for each reach.
Waters of these reaches had lower than average residue, specific conductivity, and hardness. Reaches in the Clearwater, Roseau, and Wild Rice Rivers had waters with near average CV of mean monthly discharge and average annual and May low flows. Reaches in the Red Lake and Otter Tail Rivers had waters with exceptionally high average annual and May low discharges and low CV of mean monthly discharge. Figure 24 .
