Scatter plot between log transformed values of HP1 (a) and HP2 (b) with Range of PPM (1), catchment area (2), lake percentage (3) across the studied area. We further divided studied rivers as high-head hydropower plants (HHH), and run-of-the-river hydro power plants (ROR). Circular points show values for ROR type gauging stations and triangular points for HHH type gauging stations. Horizontal line going across the plots are threshold limit values for HP1 and HP2 and black line is the linear trend line. R squared and p-values are shown for variables displaying a statistically significant trend.
