 note = {In the Lake Ikeda, we have carried out the measurement of the intensity of the underwater
light by means of photovoltaic cell in every month from August 1965 to May 1967 inclusive
(Fig. 1). The results are as follows:
(1) The Lake water mass is divided optically into two layers, that is, the upper one and the
lower. Seasonal variation at three stations is quite similar (Fig. 3).
(2) The extinction coefficient is at its maximum in December, when the starch manufactories
round the Lake, which begin their operations in October, finishing them in February, are in the
full operation. This fact may be attributed to an effect of the starch-dregs on the extinction
coefficient.
(3) The extinction coefficient μ is related to the transparency T by the expression : μT=1.5
