The tree from comment 6346 is still there. Photo is at 11 cms

Ran on 14.5 on morez. With all the additional, this was more like 25 at the put in. after the hydro comes back in. No wood. Really awesome at this level, 4+ moves with class 5 consequences. Continuous and smooth. All scoutable. Can support a bit more water, but not a lot more since the mini canyon in was pretty full for us. Perhaps we glided over all the trees?

Ran today to Lezat, with 5cms, everything runnable, no portages. One dangerous tree in a gorge, runnable with a somewhat sketchy line.

Étroits de la Bienne: la dent de requin (le S) est infran, un arbre s’y est coincé. Si non elle est en bonne état. 4 m3/sec à Morez = 1.17 m à l’usine de Tancua. Navigation fluide.

After the gorge it is possible to take-out on river-right at 46.49553,5.94262 and walk up a track to the road at Lézat. Nothing wrong with the track but the height gain is 150m vertical. You might prefer the class II-III paddle out.

Ran part 1 (only) with 5 m3/s at Morez. A perfectly entertaining level. Strong currents in the drops but not pushy in the pools. The above-grade paddlers in the group did not have to portage anything at this level.

All clear. Remarkably little wood in the water.

Run with 13 m3/s in Morez, super nice, super smooth. this water level is super nice. Be careful to have a look (from the right river bank) before entering the "klamm section". It is forbidden to swim, there are too many trees on and in the water. To be honnest I think the maximum could be very high but you need to know the river!

Very nice run that can be divided in two parts:

- Part 1: wild gorge with 2 difficult rapids (class IV, IV+ or X depending on the level). Those can be carried on the right side. Be careful with the banks on the second rapid, they can be very slippery!

- Part 2: class III rapids between Lezat and La Rixouse.

We did the full section on the 2/4/16 with a level of 4,2m3/s in Morez. It was a good level to discover the gorge. A bit low for the section between Lezat and La Rixouse.
