Peruvian river
At the mouth it carries 26 m³/s on average: an Olympic pool every 96 seconds. It drops from 4,274 m to 0 m, 24 m per kilometre on average. Its basin covers 3,389 km², about the size of CV. 2.6 million people live in it. Highest water: from February to March; lowest: from June to August and November. Its dams hold back little of its water (5.7% of a year's flow).

Rímac River, month by month
Highest water: from February to March
Lowest water: from June to August and November. Best months to visit: from January to May.
From about 4.4 m³/s in the lowest month to 60 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.
