River in Finland
At the mouth it carries 17 m³/s on average: an Olympic pool every 148 seconds. It drops from 52 m to 6 m, 0.7 m per kilometre on average. Its basin covers 885 km², about the size of HK. 161,000 people live in it. Highest water: April; lowest: from January to March and July. No large dam holds it back: it is one of the world's free-flowing rivers.

Aura River, month by month
Highest water: April
Lowest water: from January to March and July. Freezing months (average below −4 °C): from January to February. Best months to visit: from June to August.
From about 5.5 m³/s in the lowest month to 55 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.
