Weir
Also: weir, low-head dam
A weir is an artificial step in the river. It's one of the most dangerous obstacles of all, because holding holes form below it.

Many German rivers are dammed by weirs, even on otherwise gentle stretches. Often there are boat chutes, portages or locks. If not: land early and portage. On our Rur trip from Jülich to Roermond we had to portage several weirs.
