River in northern Nevada, United States
At the mouth it carries 11 m³/s on average: an Olympic pool every 227 seconds. It drops from 1,713 m to 1,171 m, 1.0 m per kilometre on average. Its basin covers 42,994 km², about the size of DK. 67,000 people live in it. Highest water: from February to April; lowest: January and from August to October. It is heavily dammed: reservoirs can hold 105% of a year's flow.

Humboldt River, month by month
Highest water: from February to April
Lowest water: January and from August to October. Best months to visit: from May to September.
From about 0.0 m³/s in the lowest month to 78 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.
