There is a river that can change the direction of flow





There is a river, which periodically change places the source and the mouth. If lakes are located at the same height above sea level, the water level in them depends on the direction of flow of the river connecting the lake, and from fluctuations in the groundwater level. And the last, in turn, has a direct impact on the direction of the river. After all, when the level of groundwater under one lake, and it raises the water level and river flow is directed towards a shallow lake, and vice versa. Such a phenomenon is peculiar, such as Shuya river connecting with Lake Suojarvi Shotozero.
