How does Lake Constance affect the Rhine River’s flow?

Lake Constance plays a significant role in regulating the Rhine River’s hydrology. As the river enters the lake, its current slackens, forming a delta. The lake acts as a natural buffer that evens out variations in the river's flow, which is otherwise characterized by a torrential Alpine regime prone to high water levels from spring and summer snowmelt. Additionally, the lake functions as a filter for the water passing through it. After exiting the lake via the Untersee arm, the river continues its course as the Hochrhein.123
