Water level along the river (RiverATLAS; the height is exaggerated). Towns: GeoNames and Wikidata; bridges, dams and tributaries: Wikidata.
Left and southern tributary of the river Elbe in Lower Saxony, Germany
At the mouth it carries 804 m³/s on average: an Olympic pool every 3.1 seconds. It drops from 63 m to -1 m, 0.5 m per kilometre on average. Its basin covers 2,852 km², about the size of LU. 20.7 million people live in it. Highest water: March, from May to June and December. Dams and reservoirs hold back a large share of its water (14% of a year's flow).

Ilmenau, month by month
Highest water: March, from May to June and December
Best months to visit: from May to September.
From about 430 m³/s in the lowest month to 1,500 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.
