The Lizerne (in the upper reaches of Lizerne de la Mare , formerly Liserne ) is an approximately 15 kilometer long tributary of the Rhône in the canton of Valais. It rises in a high valley near the border with the canton of Vaud below the peaks of Sex Rouge , Tête Noire (2,451 m) and La Fava (2,612 m). The source tributaries form several rivulets in an alpine scree field . Only a few 100 meters below this source zone is a small reservoir that is used to control the water supply.

In its middle course it takes in the Derbonne torrent (also called Lizerne de Derborence in the lower reaches ) coming from the west, which previously left the Lac de Derborence . After around 15 kilometers, the Lizerne joins the Rhône near Ardon .

In the middle of the stream there is a gorge with almost vertical rock walls. A small road that leads from the village of Vétroz passes this gorge with the help of several small, winding and unlit tunnels. At the exit of this gorge there is a hydroelectric power station that receives its supply from the catchment area of ​​the Lizerne. In the immediate vicinity you can see the artificial course of an old bisse , which was hung on the rock wall.

The water in the Lizerne is partly used for drinking water. The municipality of Vetroz participates in this in a special way, drawing it with pumps at three points.
