This is supposed to be due to the inflow of the mud-water occasioned by the rain-fall. The extinction coefficient of the lower layer during the period from August to September is larger than that of the upper layer. This is supposed to be due to the circulation of the lake-water caused by the water-temperature-difference. 3) The enlargement of the extinction coefficient observable from Autumn to winter was confirmed to be caused by the effect of the starch-dregs.}, pages = {64--72}, title = {池田湖における水中照度の消滅係数(続)}, volume = {17}, year = {} }
