Just a quick addition.
The levels page on eauxvives doesnt cover the department of hautes alpes. (Most of the runs round Briancon)
It does cover the Alps north of Grenoble, the region round Gap, and from the Ubaye southward. (Although the Ubaye gauge is unreliable)
It also covers the whole pyrenees (french & spanish), massif central and southern switzerland
If youre ever in the Nice area we ran the Esteron. A fantastic, hard run in 2 amazing gorges. Unfortunately rain fed but if its up its well worth the drive!
