Its basin covers 35,400 km², about the size of TW. 508,000 people live in it. Highest water: from January to March; lowest: from July to October. No large dam holds it back: it is one of the world's free-flowing rivers.

Acre River, month by month
Highest water: from January to March
Lowest water: from July to October. Best months to visit: from June to August.
From about 250 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.
