Tributary of the Amazon river
At the mouth it carries 30,000 m³/s on average: 12 Olympic pools every second. It drops from 198 m to 7 m, 0.1 m per kilometre on average. Its basin covers 720,114 km², about the size of ZM. 17.7 million people live in it. Highest water: from May to July. No large dam holds it back: it is one of the world's free-flowing rivers.

Rio Negro, month by month
Highest water: from May to July
Best months to visit: from May to August and November.
From about 96,400 m³/s in the lowest month to 171,600 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.
