Ohře
Template:Short description Template:Distinguish Template:Infobox river The Ohře ({{#invoke:IPA|main}}), also known in English and German as Eger ({{#invoke:IPA|main}}), is a river in Germany and the Czech Republic, a left tributary of the Elbe River. It flows through the Bavarian district of Upper Franconia in Germany, and through the Karlovy Vary and Ústí nad Labem regions in the Czech Republic. It is Template:Convert long, of which Template:Convert is in the Czech Republic, making it the fourth longest river in the country.
EtymologyEdit
The name is of Celtic or pre-Celtic origin. In the 9th century, it appeared as Agara. According to one theory, its meaning was 'salmon river' (composed of the words ag, eg – 'salmon', and are, ara – 'flowing water').<ref name=pohhistory>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Another theory suggests that the name was derived from agriā and meant a fast-moving, fast-flowing river. In the 12th century, Ohře was written as Egre, Oegre and Ogre.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
CourseEdit
"Eger, sprich, wo eilst du hin?"
"Zu der Elbe", rauscht es reger,
"Zu der Elbe muß ich zieh'n!"
Als der Knabe kam zur Elbe,
War die Antwort inhaltsschwer;
Donnernd braust zurück dieselbe:
"Und ich muß ins deutsche Meer!"
When the boy came to the Ohře:
"Ohře, speak, where are you rushing to?"
"To the Elbe", whooshes it astirly,
"To the Elbe I must draw!"
When the boy came to the Elbe,
The answer was profound;
Thundering booms back the selfsame:
"And I must (go) into the German Sea!"
The Ohře originates in the territory of Weißenstadt in the Fichtel Mountains at an elevation of Template:Cvt, below the Schneeberg mountain. It flows to Litoměřice, where it enters the Elbe River at an elevation of Template:Cvt.<ref name=poh>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The Ohře flows through the Fichtel Mountains in an eastward direction, through Lake Weissenstadt (Weißenstädter See) and through the towns of Röslau and Marktleuthen, and, after almost 50 km, reaches the Czech-German border near Hohenberg an der Eger. It then flows through the historic region of the Czech Republic which was known until 1945 as Egerland. The river passes the towns of Cheb, (Template:Langx, like the river), Loket, Sokolov, Karlovy Vary, Klášterec nad Ohří, Kadaň, Žatec, Louny, Libochovice, Budyně nad Ohří and Terezín before flowing into the river Elbe at Litoměřice.

The German part of the river (including the border section) is Template:Cvt long.Template:GeoQuelle
The highest volume flow rate occurs in spring. The average volume flow rate at the mouth is 37.94 m³/s.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The lower part of the river flows through areas with the lowest average precipitation in the Czech Republic (400–500 mm).<ref name=poh/>
