It flows into the Indigirka in 1,086 kilometres (675 mi) from its mouth. There is black coal deposit in the river basin. The district centre – the village of Khonuu – is located at the mouth of the river.
The name comes from the Evenki language, “мома” means "wood, timber, tree". This is the name for the rivers with steep, easy to wash banks that crumble together with trees growing on them, cluttering the river bed.
