3.1.4. Drains discharging to Lake Edko
CCME WQI values of Edko Drain indicated that the water quality for aquatic uses can be mostly rated as marginal.It had the variation in WQI score (50–73) according to the year (Fig. 7). A high P value (P = 0.346) suggests that an independent variable (X, years) is having a small impact on the dependent variable (Y, WQI). In addition, temporal changes in year of measurement (X) can explain only 9.9% of the temporal variability observed in the WQI (Table 3).
