Oued Mellègue, month by month
Highest water: from January to February
Lowest water: from June to September. Best months to visit: from April to June and from September to October.
From about 1.8 m³/s in the lowest month to 35 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.
