River
At the mouth it carries 70 m³/s on average: an Olympic pool every 36 seconds. It drops from 528 m to 88 m, 1.9 m per kilometre on average. Its basin covers 12,700 km², about the size of BS. 5.7 million people live in it. Highest water: from March to May; lowest: from January to February. Its dams hold back little of its water (6.5% of a year's flow).

Sajó, month by month
Highest water: from March to May
Lowest water: from January to February. Best months to visit: from May to September.
From about 200 m³/s in the lowest month to 1,300 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.
