Its basin covers 17,851 km², about the size of KW. 200,000 people live in it. Highest water: from May to July. No large dam holds it back: it is one of the world's free-flowing rivers.

Coca River, month by month
Highest water: from May to July
Best months to visit: from January to May.
From about 900 m³/s in the lowest month to 1,600 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.
