put in at the bridge after the dam end take out at the end of the lake. Mainly is runnable after big rain when boite standard section is at a medium flow but it depends a lot by the releases of the dam of Vodo. there is not a clear reference whit any idrometers. the run is made out of 3 canyon and it can be quite hard whit high flow… a lot of tree and no escape or at least very hard in some places. you can see my video about Canyon boite whit medium/low flow.
