At the mouth it carries 350 m³/s on average: an Olympic pool every 7.1 seconds. It drops from 604 m to 104 m, 0.6 m per kilometre on average. Its basin covers 55,800 km², about the size of HR. 150,000 people live in it. Highest water: from May to July; lowest: from January to April. No large dam holds it back: it is one of the world's free-flowing rivers.

Biryusa, month by month
Highest water: from May to July
Lowest water: from January to April. Freezing months (average below −4 °C): from November to March. Best months to visit: from June to August.
From about 47 m³/s in the lowest month to 940 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.
