River in Komi Republic, Russia, tributary of Pechora
At the mouth it carries 1,310 m³/s on average: an Olympic pool every 1.9 seconds. It drops from 102 m to -166 m, 0.5 m per kilometre on average. Its basin covers 93,600 km², about the size of HU. 155,000 people live in it. Highest water, with the snowmelt: from June to July; lowest: from January to April. No large dam holds it back: it is one of the world's free-flowing rivers.

- JulyThe best months to visit
Usa, month by month
Highest water: from June to July
Lowest water: from January to April. Freezing months (average below −4 °C): from November to April. Melting snow makes up much of its water. Best months to visit: July.
From about 260 m³/s in the lowest month to 7,600 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
