Source-derived summary

The Desaguadero River, also known as Risawariru or Uchusumain, is a river shared between Bolivia and Peru. It drains Lake Titicaca from the southern part of the river basin, flowing south and draining approximately five percent of the lake's flood waters into Lake Uru Uru and Lake Poopó. Its source in the north is very near the Peruvian border.

It is navigable only by small craft and supports indigenous communities such as the Uru Muratu community.

Editorial summary

Begin with the source’s own compact description: “Desaguadero River (Bolivia and Peru)” is river in Peru. The dossier treats that line as a proposition to test through Desaguadero, River and Bolivia, not as a finished interpretation.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current 85-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Desaguadero, River and Bolivia is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “river in Peru” 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

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 Aug 2, 2026. The linked authority identifier is Q1343322. VIAF identifies the subject as 316432600. The Library of Congress control number is sh2009008847. Authority coordinates are -18.435, -67.090. 3 of 5 selected statements include explicit references; 2 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 source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
