    The Crescent Dam was built between 1929 and 1932. A gravity dam, it is 330 meters long and 37 meters high. Its width at the base is 24 meters and at the crest 3.5 meters. It was built on the initiative of SA Compagnie HydroElectrique de la Cure and was owned by the City of Paris until 1946. The dam was built to regulate the waters of the Yonne and Seine rivers and thus prevent flooding in Paris, while also producing electricity. More than 165 hectares of cultivated land, hamlets, mills, and paths were flooded to allow the creation of the reservoir (maximum depth of 40 meters). It occupies four municipalities and two departments, and is fed by the Cure and Chalaux rivers. The structure was partly financed by war reparations owed by Germany to France after the First World War. This is why much of the dam's mechanisms are German-made.
    The road across it is narrow and only allows passage for one vehicle. Fortunately, there is very little traffic.
