Lac des Sapins
reservoir in France
Lac des Sapins, literally translated into English as 'the lake of the fir-trees', is an artificial lake located in the region of Rhône-Alpes. It is situated 65 km northwest of the city of Lyon.
History
Construction of the lake began in the summer of 1967 by Louis Gueydon. The lake was built to try to develop the tourist industry in the region after a decline in industry in rural areas. In 1983, a camping park next to the lake was built with chalets, caravans etc. The investment proved successful, and in 1990, the camping park was extended, with the chalets and caravans upgraded or renovated. Multiple sports activities were proposed (mountain biking, wind-surfing, volleyball and acrobranching).
This brief starts where responsible research should: with the source description of “Lac des Sapins” as reservoir in France. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as reservoir in France. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q3215684. Authority coordinates are 46.007, 4.371. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1967, 1983 and 1990.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
