River in Norway
At the mouth it carries 219 m³/s on average: an Olympic pool every 11 seconds. It drops from 567 m to 85 m, 2.4 m per kilometre on average. Its basin covers 11,459 km², about the size of QA. 45,000 people live in it. Highest water, with the snowmelt: from May to July; lowest: from January to April. Its dams hold back little of its water (2.0% of a year's flow).

Gudbrandsdalslågen, month by month
Highest water: from May to July
Lowest water: from January to April. Freezing months (average below −4 °C): from December to March. Melting snow makes up much of its water. Best months to visit: from June to August.
From about 33 m³/s in the lowest month to 730 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.
