This paper describes thermal stratification in lakes, its property of flux by destruction, and water quality transportation from results observed in field survey for Lakes Hibara, Onogawa and Akimoto. Its main conclusions by the above-mentioned ways are shown in the following.
On the Whole, these lakes shows clearly not only thermal stratification in summer but also its destruction processes with the fall of water temperature. These lakes indicate a similar tendency of formation of thermal stratification in the vertical direction. Lake Hibara has clear processes of thermal stratification and of its destruction. Lake Onogawa has a tendency toward water stagnation. Lake Akimoto has a remarkable distribution for turbidity in the vertical direction.
