River between Colombia and Venezuela
At the mouth it carries 800 m³/s on average: an Olympic pool every 3.1 seconds. It drops from 3,123 m to 30 m, 3.4 m per kilometre on average. Its basin covers 25,000 km², about the size of MK. 347,000 people live in it. Highest water: from July to August; lowest: from January to April. No large dam holds it back: it is one of the world's free-flowing rivers.

Arauca River, month by month
Highest water: from July to August
Lowest water: from January to April. Best months to visit: from December to February.
From about 390 m³/s in the lowest month to 1,400 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.
