Etymology

Like some other names in Bohemia, the name Jizera is of Celtic origin, as the Celtic Boii (hence the Germanic word Bohemia, home of the Boii) lived in the area before the Roman times (see also the Isar in Germany, the IJzer in Flanders and the Isère in France) before assimilation by the Marcomanni and later Germanic and West Slavic peoples.[2]

Geography

The river develops from the confluence of the Velká Jizera (Great Jizera) in the Jizera Mountains and the Malá Jizera (Little Jizera) in the Giant Mountains, and flows for 164 km into the Elbe in the municipality of Káraný near Brandýs nad Labem-Stará Boleslav. On its way, it intersects the Ještěd-Kozákov Ridge. For the first 15 kilometres, the river constitutes the border between Poland and the Czech Republic.

Water resource

Jizera is also one of two biggest resources of potable water for the city of Prague and other neighboring villages and towns (the second one is Želivka). From Benátky nad Jizerou to its on-flow, it is surrounded by bank infiltration system, and in the municipality of Sojovice the water is being pumped for artificial infiltration.[3]
