River in Kochi and Tokushima prefectures, Japan
At the mouth it carries 136 m³/s on average: an Olympic pool every 18 seconds. It drops from 597 m to -3 m, 2.5 m per kilometre on average. Its basin covers 3,750 km², about the size of CV. 443,000 people live in it. Highest water: from June to July and September; lowest: from December to February. Dams and reservoirs hold back a large share of its water (11% of a year's flow).

Yoshino River, month by month
Highest water: from June to July and September
Lowest water: from December to February. Best months to visit: from April to May and from October to November.
From about 58 m³/s in the lowest month to 250 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.
