River in Afghanistan and Iran
At the mouth it carries 78 m³/s on average: an Olympic pool every 32 seconds. It drops from 3,320 m to 477 m, 2.5 m per kilometre on average. Its basin covers 500,000 km², about the size of ES. 6.0 million people live in it. Highest water: March; lowest: from August to November. Dams and reservoirs hold back a large share of its water (20% of a year's flow).

Helmand River, month by month
Highest water: March
Lowest water: from August to November. Best months to visit: from April to May and from September to October.
From about 63 m³/s in the lowest month to 2,100 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.
