By results of seasonal measurements of spectral transparency and concentration of chlorophyll a dependence is found in water of different-type lakes of Altai Krai during 2011–2013 between these indicators, presented in the form of approximating curve, satisfying the Bouguer law. The analysis of the obtained experimental data taking into account disperse structure of particles (cages) of seaweed phytoplankton is carried out.
