Paro Chhu, month by month
Highest water: from July to August
Lowest water: from December to March. Best months to visit: from April to June and from September to October.
From about 2.5 m³/s in the lowest month to 98 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.
