Source-derived summary

Ayun Hạ Reservoir or Ayun Hạ Lake (Vietnamese: Hồ Ayun Hạ) is an artificial lake in Gia Lai Province, Vietnam. The lake was formed when the Ayun River was stopped early in 1994, to start the construction of a dam and lake for irrigation. The flooded area of the lake district belongs to the commune of HBong Chu Se.

The lake has a surface area of 37 km2 (14 sq mi), and has a length of 25 km (16 mi), and is 5 km (3.1 mi) at its widest.

Editorial summary

Begin with the source’s own compact description: “Ayun Hạ Reservoir” is lake in Vietnam. The dossier treats that line as a proposition to test through Ayun, Reservoir and lake, not as a finished interpretation.

Editorial reviewMost useful as a place-based finding aid connecting the present description to earlier jurisdictions, maps and built evidence. The current lead gives the account dated anchors—1994—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Ayun, Reservoir and lake is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “lake in Vietnam” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

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 24, 2026. The linked authority identifier is Q4831830. Authority coordinates are 13.584, 108.258. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1994.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. 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.
