A walk along the last part of the Alpine Rhine, right before it enters the Lake of Constance.
This part of the river is heavily regulated and is basically an artificial canal. The canal bed reaches far into the Lake of Constance and bends towards the west to keep the river from silting up the eastern part of the lake and eventually cutting off a part of the lake.
I think the photos date back to 2017.
