Lac d'Orédon, Artificial reservoir in Hautes-Pyrénées, France
Lake Orédon covers an area of 0.46 square kilometers at an elevation of 1849 meters in the mountains of Hautes-Pyrénées.
Built in 1880, this reservoir became one of the first large artificial lakes in France, created to regulate water resources in the region.
The Orédon refuge, initially built to house engineers during dam construction, now welcomes hikers and naturalists throughout the summer season.
The lake enables hydroelectric power generation, irrigation of agricultural lands, and supplies drinking water to surrounding municipalities.
The waters of the lake flow from Lake Cap-de-Long and discharge into the Neste River, forming an interconnected hydraulic system.

The lakes of Occitanie, located between the Pyrenees and Massif Central, consist of both natural and artificial water bodies. The natural lakes are mainly found at high altitudes in the Pyrenees, formed by glacial activity. The artificial lakes, created by dams, serve as water reservoirs and host water activities. This region features notable lakes such as Salagou with its red rocks, Lac d'Oô with its 300-meter waterfall, and Lac de Gaube facing Vignemale.
