Editorial summary

This brief starts where responsible research should: with the source description of “Lake Udyl” as lake in Khabarovsk Krai, Russia. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current 54-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 Lake, Udyl 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 lake in Khabarovsk Krai, Russia. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 27, 2026. The linked authority identifier is Q2229990. Authority coordinates are 52.145, 139.889. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

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.
