These water quality parameters variables indicate that Lakes
Manyame and Chivero are highly eutrophic and variables were
positively correlated with each other. The correlation between
TSM and chl_a indicated that TSM included the backscatter caused
by the inorganic parts of the phytoplankton (Dekker et al., 2002;
Song et al., 2011). The concentrations of TSM (Fig. 3) were higher
in Lake Manyame than in Lake Chivero therefore, the reservoir’s
apparent reflectance which indicated a high TSM backscattering
in the infrared and NIR bands.
