Coyllococha
dam in Junín Region
Coyllococha (possibly from Quechua quyllu impeccable white; generic name for a kind of potatoes, qucha lake,) is a lake in Peru located in the Junín Region, Huancayo Province, Chongos Alto District. It is situated at a height of approximately 4,683 metres (15,364 ft), about 4.15 km long and 1.45 km at its widest point. Coyllococha lies southwest of Yurajcocha and Huichicocha. It belongs to the watershed of the Mantaro River.
The lake is sometimes also named Coyllorcocha (possibly from Quechua quyllur star, "star lake"). This name correlates with the name of mountain at the western end of the lake whose name is Coyllor (Quyllur).
In 1999 the Coyllorcocha dam was erected at the northeastern end of the lake at 12°34′49.6″S 75°32′22.6″W. It is 5.5 m (18 ft) high. It is operated by Electroperu.

Why this record matters
The phrase “dam in Junín Region” 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.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 1, 2026. The linked authority identifier is Q15270809. Authority coordinates are -12.590, -75.554. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1999.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
