Source-derived summary

Lac de Cleuson is a reservoir in the municipality of Nendaz, Valais, Switzerland. Its surface area is 0.51 km2 (0.20 sq mi). Water from the reservoir is often pumped into the Grande Dixence Dam's reservoir, Lac des Dix, for use in hydroelectricity production.

Editorial summary

This brief starts where responsible research should: with the source description of “Lac de Cleuson” as artificial lake in Switzerland. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewMost useful as a place-based finding aid connecting the present description to earlier jurisdictions, maps and built evidence. The current 43-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Cleuson, artificial and lake can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the places & architecture register because the source frames it as artificial lake in Switzerland. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q676804. Authority coordinates are 46.110, 7.323. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. 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.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
