Kempendyay (river)
river in Yakutia, Russia
The Kempendyay (Russian: Кемпендяй; Yakut: Кэмпэндээйи) is a river in Yakutia (Sakha Republic), Russia. It is a right hand tributary of the Vilyuy, with a length of 266 kilometres (165 mi) and a drainage basin area of 3,100 square kilometres (1,200 mi2).
The river flows across the mostly uninhabited territory of Suntarsky District. Kempendyay village is located in its middle course. Ustye village lies near its confluence with the Vilyuy, and Suntar, the administrative center of the district, lies a little to the west on the facing bank. There are deposits of rock salt in the Kempendyay basin, as well as a mud bath resort.
Course
The Kempendyay begins in the Lena Plateau and flows within it along its course. It heads first roughly southwestwards and in its last stretch, shortly after Kempendyay village, it bends and heads northwestwards strongly meandering within a floodplain among oxbow lakes. Finally the river joins the right bank of the Vilyuy 737 kilometres (458 mi) from its mouth. The Kempendyay freezes between the second half of October and late May.

Why this record matters
“Kempendyay (river)” is worth following because a concise public description often conceals a longer documentary argument. Here, Kempendyay, river and Yakutia provides the most credible route into that argument.
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 Sep 12, 2026. The linked authority identifier is Q2359100. Authority coordinates are 62.304, 119.887. 3 of 3 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank.
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.
