Description

The Gage dam, located in the commune of Cros-de-Géorand, serves as a regulating reservoir for the Montpezat hydroelectric plant. It measures 39.6 meters in height, 172 meters in length, between 1,50 meters and 5,60 meters in width. Fishing authorized.

The Gage dam (known as the Moulin de Peyron dam) was filled with water in 1954 and holds back a volume of 3 thousand m³ over an area of ​​410 hectares. It is fed by the Gage and Thauron rivers.

The Gage dam is part of a network of several reservoirs (La Grange, Lake Issarlès, La Palisse) designed to capture and store water from the Ardèche plateau. Thanks to a network of galleries of nearly 25km, the water is transported to the underground plant of Montpezat under Bauzon.

It is one of the dams which play a significant role in supporting low water levels in the Ardèche and the Loire.

Between 1965 and 1966 the Gage dam was reinforced by the construction of a new dam (Gage II) directly upstream of the first.
From 2013 to 2018, a flood spillway was built on the Gage dam in order to withstand the passage of a thousand-year flood (675m3/s).
