Use the gauge at the bridge at take-in. 50 is a solid medium water run. When you don’t run any of the portage, the run doesn’t eclipse class 4.
At this level, the canyon about halfway will get tricky though. Either bony drop on river right or nasty undercut.
Everything else is open waves with nothing too serious.

Logjam from 05.05.2023 should be cleared.
