The whole river gets channeled into tubes right before a weir. Mandatory take out on the river left underneath a sign. It is an easy stop on the drive up if you want to see it from the bank.
With low water (-0,01 @Cantoira) it’s a pretty easy stop.

New hydro scheme. River wide pipe bridge strainer before the weir. Almost certain death

Kurz vor dem Wehr liegen die Röhren eines alten Röhrendammes kreuz und quer im Fluss, je nach Wasserstand teilweise über, teilweise unter Wasser. Extrem gefährlich als Schwimmer.

Shortly before the Dam there are the Tubes of an old Tube Dam laying across the whole riverbed. Extremly dangerous when swimming.
