The Ohře (Czech: [ˈoɦr̝ɛ]) or, slightly less commonly in English sources, the Eger (German: [ˈeːɡɐ] (listen), Czech also: Oharka or Ohara, Celtic: Agara, Polish: Ohrza), is a 316 km river[1] in Germany (50 km) and the Czech Republic (266 km),[2] left tributary of the Elbe. The river's catchment area is 5,588 km²,[1] of which 4,601 km² is in the Czech Republic,[2] 920 km² in Bavaria[3] and 67 km² in Saxony. It is the fourth-longest river in the Czech Republic.

Several districts in Germany and the Czech Republic have formed a Euroregion initiative, Euregio Egrensis, to foster co-operation in the region.

Etymology

There is a Czech pun that the Ohře got its name from the river Teplá (meaning "warm" in Czech)—"ohřát" means "to warm up". However, the real origin, which also shows in the German name, is Celtic, from Agara (the "Salmon River"). The records show the name as Agara, Agira, Agra in the 9th century, Egire, Egra or Ogra in the 11th century and Eger in 1472.[4]

Sources

The source of the river Eger is situated in Bavaria at the foot of the Schneeberg in the Fichtel Mountains near the town of Weißenstadt.

The river then flows through Lake Weissenstadt and the towns of Roeslau, Marktleuthen and Hohenberg where it leaves Germany. After about 35 km, the Eger (not to be confused with the town in Hungary), as the river is called in German, crosses the border into the Czech Republic to flow through parts of Bohemia which were known until 1945 as Egerland. The river passes the towns of Cheb, (German: Eger, like the river), Karlovy Vary, Klášterec nad Ohří, Kadaň, Žatec, Louny, and Terezín before flowing into the river Elbe at Litoměřice. The river basin of the Ohře is part of formerly German speaking Sudetenland still having many toponyms from German.

Flow

The highest volume flow rate occurs in spring. The average volume flow rate at the mouth is 37.94 m³/s. The lower part of the river flows through areas with the lowest average precipitation in the Czech Republic (less than 500 mm).

Use

The Ohře is primarily used for irrigation and hydroelectric energy. There are two dams: Skalka (built in 1962–1964, area 378 ha) and Nechranice (built 1961–1968, area 1338 ha). The river flows through the following important towns: Cheb, Sokolov, Loket, Karlovy Vary, Ostrov nad Ohří, Klášterec nad Ohří, Kadaň, Žatec, Louny, Libochovice, Budyně nad Ohří, Terezín and Litoměřice.
