The Ohře (pronounced [ˈoɦr̝ɛ]; German: Ltspkr.png Eger, Czech also: Oharka or Ohara, Celtic: Agara, Polish: Ohrza) is a 316 km long river in Germany (65 km) and the Czech Republic (251 km), left tributary of the Elbe. The catchment area of the river is 6,255 km2, of which 5,614 km2 is in the Czech Republic and 641 km2 in Germany. It is the third biggest river in the Czech Republic.

Several districts in Germany and the Czech Republic have formed an Euroregion initiative named Euregio Egrensis to foster cooperation in the region of Eger/Ohře/Cheb.


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.[1] Another theory states that since in Macedonia there exists a Lake Ohrid, the Slavic people who settled in the Balkans, particularly Macedonia around Lake Ohrid, originated from the area of the river Ohře and thus named the lake in south Macedonia "Ohrid".


Source of the Eger (Ohře).

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

The river then flows through the Weissenstadt Lake 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 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).


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.
