metres (51,000,000 cu ft). In 1880, when the canal company went bankrupt, the dam was converted into a source of drinking water for the inhabitants of Rive-de-Gier. It delivers 245 litres (54 imp gal; 65 US gal) per second of water. The water serves 95% of the municipality of Rive-de-Gier, part of Châteauneuf, and since 2005 St-Martin-le-Plain and St. Joseph. As of 2010 19,678 people relied on the dam for water, as well as various industrial users such as

The lower one follows the original course of the river, and is used to remove silt from the reservoir. The upper one has valves where it exits the reservoir. There are two spillways with a combined length of 40 metres (130 ft).
