The lake is located in the heart of the Catalan Pyrenees Regional Natural Park.
It was created following the construction of a dam on the Aude River to support regional hydroelectric needs.
The water temperature remains quite cool even in mid-summer, often staying below 20°C.
The area is home to diverse fauna, including migratory birds and mountain marmots in the adjacent slopes.
The lake area provides a direct view of the Pic de la Calvet and the Roc d'Aude.
The trail circling the lake is accessible to mountain bikers and is part of a larger network of Capcir cycling routes.
The reservoir is used for fire-fighting water collection by aircraft during the dry summer months.
Lac de Matemale is a 213-hectare artificial reservoir situated at an altitude of 1,540 meters in the Capcir plateau of the French Pyrenees. Fed primarily by the Aude River, the lake was created in 1959 primarily to regulate water flow for hydroelectric power generation. The site serves as a recreational hub, offering a beach area and a leisure center known as 'Base de Loisirs.' During the summer months, the lake provides opportunities for swimming, stand-up paddleboarding, and pedal boat rentals. Surrounding the perimeter is a flat, 12-kilometer trail frequently used by hikers, cyclists, and trail runners. The landscape is dominated by dense pine forests and views of the Cambre d'Aze massif. During winter, the lake serves as a visual backdrop for the nearby Les Angles ski resort activities. It is a popular location for high-altitude sports training due to its elevation.

Bring layers, as the high-altitude weather can change rapidly even in mid-summer.
The perimeter path is well-marked but largely unshaded; wear sun protection.
Check the local wind reports if planning to rent a sailboat or paddleboard.
Do not attempt to swim in areas designated for water sports or boat traffic.
Leisure activities and lifeguard services are primarily active from June through early September.
Respect the 'Leave No Trace' principle; pets must be kept on a leash in designated swimming areas.
