Foto of the 2nd step at St. Jakob after the recent construction. Water pushed the the left now, room for fish on the right. 17m³/s.

Despite the warnings and the circumstances for that section I would sign, there's a new gauge that is direct on that section. Maybe someone is able to calibrate this section with the closeby gauge at https://egov.stmk.gv.at/at.gv.stmk.hydavis-p/pub/praesentation/index.xhtml?messcode=2002&ansichtstyp=karte&stationsstatus=ONLINE

Befahrung heute bei 4.2 m3/s. Die Stelle vor dem Schlitz, die normalerweise ganz links gefahren wird, sah ungemütlich aus wegen Steinen in der Landung (siehe Foto). Wir sind mittig auf dem Felsen wieder eingestiegen. Das Kehrwasser gleich danach (links vor dem Schlitz) war fast nicht vorhanden. Der Schlitz selber war aber gut fahrbar. Einige Bäume im Bach aber umfahrbar. Bei der Baustelle am Ausstieg ist die Durchfahrt aktuell frei, ist aber ein Fahrverbot.

At 85 m3/s the section took 1 hour to paddle.

Put-in below the Dam as shown on rivermap. There is access to the river downstream of the Garage between road and river.
Put-out 100m before the second of two identical bridges on riverleft.

At this discharge there are some big holes you want to avoid. But there is always a clean and obvious line around them. There are nice big wave trains. Eddies partly between the trees, so be careful when approaching the river banks. Outside of bends with dangerous trees, watch out.

WW II-III still holds at this discharge.

Pictures shown in downstream direction. Typical rapids.
There is one rapid in the lower half, that has three big holes and is alittle more tricky but still with an obvious line.

extended and definitely the last take-out before the gorge starts is at: 47.01300,12.39810 . Acessable only by feet.

Le recenti disavventure geologiche hanno reso impraticabile la Calancasca da Arvigo fino al lago di Buseno. Oltre ai danni causati da alcune frane sono in corso dei lavori per la messa in sicurezza della strada.

Als pegel Referenz könnte man evtl Rhone Gletsch nehmen.. Am Zeitpunkt der befahrung hatte es dort 9m3/s
