Water level along the river (RiverATLAS; the height is exaggerated). Towns: GeoNames and Wikidata; bridges, dams and tributaries: Wikidata.
River
At the mouth it carries 54 m³/s on average: an Olympic pool every 46 seconds. It drops from 834 m to 565 m, 2.4 m per kilometre on average. Its basin covers 954 km², about the size of HK. 255,000 people live in it. Highest water: March; lowest: from December to February. Its dams hold back little of its water (5.0% of a year's flow).

Loisach, month by month
Highest water: March
Lowest water: from December to February. Best months to visit: from June to September.
From about 35 m³/s in the lowest month to 100 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.
