River in the Congo Basin and tributary of the Congo River in Central Africa
At the mouth it carries 2,471 m³/s on average: an Olympic pool every 1.0 seconds. It drops from 380 m to 288 m, 0.1 m per kilometre on average. Its basin covers 213,400 km², about the size of OM. 1.5 million people live in it. Highest water: from October to December. No large dam holds it back: it is one of the world's free-flowing rivers.

Sangha, month by month
Highest water: from October to December
Best months to visit: from December to February and from June to July.
From about 1,300 m³/s in the lowest month to 4,600 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.
