Bolshaya Chukochya
river in Yakutia, Russia
The Bolshaya Chukochya or Chukochya (Russian: Большая Чукочья; Chukot: Рэвум-Рэву, Revum-Revu) is a river in the Sakha Republic (Yakutia) of the Russian Federation. It is 758 kilometres (471 mi) long, and has a drainage basin of 19,800 square kilometres (7,600 sq mi).
Course
It has its sources in Lake Usun-Kyuel and crosses the tundra roughly northeastwards. In its lower course it flows south of Lake Bolshoye Morskoye. Finally it flows into the Kolyma Gulf of the East Siberian Sea west of the mouths of the Kolyma. Owing to its extreme northerly location the Bolshaya Chukochya freezes up in early October and remains icebound until June.
The Bolshaya Chukochya basin is located between the basins of the Alazeya and the Kolyma.
There are study sites near the Bolshaya Chukochya in order to investigate the mineral transformations in the soils affected by permafrost.

Why this record matters
“Bolshaya Chukochya” is worth following because a concise public description often conceals a longer documentary argument. Here, Bolshaya, Chukochya and river provides the most credible route into that argument.
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 Aug 2, 2026. The linked authority identifier is Q1548523. Authority coordinates are 68.049, 155.692. 2 of 2 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 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.
