Arbre visible tardivement à la fin du premier rapide . celui bloque toute la rivière à 40 cubes

L'accès aux sources de l'Ain est désormais fermé par une barrière sur le dernier 1,5km. Il est possible de récupérer les clés au centre équestre juste au dessus, il parait qu'il faut demander à une certaine Coralie. Sinon la marche à pied est sympa.

Be very careful ! there is a cave at the bottom part of the watermill fall :

Looked at this on Jan 7 and there is a large tree blocking the river 300m from the source

I would rate this section as class III (X,4).
There is a 10m waterfall which seems to be unrunnable, at least by a low water level. This can be carried on the right. 100m before this waterfall, there is a 4m drop which might be unrunnable too. A lot of water is running below a wall on the left side. Not really nice!! Can be carried on the right.

1 or 2km before Sirod, there is the "watermill fall", which is difficult to run by low water because you have a dam just before and the level at the reception of the fall can be quite low. Be careful not to damage your boat! Can be carried on the right.

We did this section on the 5th of December with a level of 10m3 at Bourg de Sirod and it was very low and difficult to run. I would for sure place the minimum at 12m3 (Bourg de Sirod) for this run.
