Lac de Thoux St-Cricq, Artificial reservoir in Encausse, France.

Lac de Thoux Saint-Cricq is a reservoir of 70 hectares spread across four communes of the Bastides de Lomagne: Monbrun, Encausse, Thoux and Saint-Cricq, between Auch and Toulouse. Its broad, flat surface of pale blue-green water carries small white-sailed boats, and a thin strip of green vegetation lines the near shore.

The dam was first filled in 1968 and holds 3.6 million cubic metres of water across 70 hectares. It was built for agriculture, letting farmers irrigate maize and soya, and a pumping station at L'Isle-Jourdain carries water from the Save through a stream into the lake to keep its level. The Compagnie d'aménagement des coteaux de Gascogne (CACG) owns and manages it.

The lake is managed by the Compagnie d'aménagement des coteaux de Gascogne (CACG), which also owns it. Water is pumped at L'Isle-Jourdain and carried several kilometres from the Save through a stream into the lake to keep its level. A sailing club and nautical base now occupy the shore, and Toulouse is 35 minutes away.

The lake lies between Auch and Toulouse, about 35 minutes from Toulouse, spread over the communes of Monbrun, Encausse, Thoux and Saint-Cricq. A nautical base, sailing club, campsite, leisure park, water park and restaurant sit on its shores; sailing, fishing, swimming, pedal boats and canoeing are practised there. The CACG manages the site.
