River in the Peloponnese, Greece
At the mouth it carries 45 m³/s on average: an Olympic pool every 56 seconds. It drops from 380 m to -1 m, 3.2 m per kilometre on average. Its basin covers 3,600 km², about the size of CV. 79,000 people live in it. Highest water: from December to January; lowest: from June to September. Its dams hold back little of its water (3.5% of a year's flow).

Alfeios, month by month
Highest water: from December to January
Lowest water: from June to September. Best months to visit: from May to September.
From about 4.6 m³/s in the lowest month to 110 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.
