This is a view of the rivelet. I expect it to be quite impressive in spring, when the (meters, I was told) of snow melt that will cover city and country in winter. But on the two occassions I was there it was hardly visible. As so often it is an open sewer. The city being in a crowded space whole blocks of it are built over the river, I know a set of toilets where the flushing is done by the river under it.
