Investigation made of the distribution of electric conductivity and inorganic component (K, Na, Ca, Mg, Cl, and SiO2) in the surface water from 44 stations of Lake Suwa. The electric conductivity and the concentration of every component were rlatively high at the stations on the shore of east side. This tendency was remarkble for Na, Cl, and SiO2, reflecting the effect of human activities. The coefficient of variation of SiO2 value for all the stations was the largest of the components in 21.4 %. It was presumed that the reason was due to the biological and chemical behaviors of SiO2 such as absorption by diatom and chemical deposition.
