I am free Friday starting at 13:00. It's nice to have a large-ish group (5 or more) to set up safety and cameras... Above 25, the ferry between #1 and #2 can be tricky if you lose balance after #1.
Note that looking at the water level graph, which appears to be stabilizing around 27 m^3/s (see below), and considering the forecasted rain, the river is very likely to rise between now and Friday. If so, it might reach 60 m^3/s (my bet).
