After coursing right through the valley, the Évançon flows into the Dora Baltea in Verrès, near the bridge of Fleuran.

The colour of the water in the stream varies from azure in the morning and when it is cold through to a grey-white towards the evening and after a hot day.

Only in winter the river is transparent, while in summer it is more or less clouded by sediment and sand from the glacier.

The stream is inhabited exclusively by trout (both brown and rainbow, repopulated annually by the regional fish consortium.

Unfortunately, in addition to harming the naturalness and aesthetic appearance of the stream, these have made it less hospitable to the trout.
