The Elbe (Czech: Labe, German: Elbe) is Central Europe's fourth-longest river (1,094 km / 680 mi), connecting the Czech heartland to the North Sea through Germany's industrial and historic core.
| Country | Section | Key Points |
|---|---|---|
| Czech Republic | Source to border (371 km) | Rises at 1,386 m on Mt. Violík (Krkonoše/ Giant Mts). Flows through Hradec Králové, Pardubice, Čáslav, Kolín, Mělník (Vltava confluence), Prague (Vltava), Litoměřice (Ohře confluence). |
| Germany | Border to North Sea (727 km) | Enters at Schmilka (Saxon Switzerland). Dresden, Meissen, Torgau, Wittenberg, Magdeburg (Mittellandkanal), Hamburg (port). Tidal from Geesthacht (130 km inland). |
| Austria | Minor headwater tributaries only | Upper catchment of the Vltava (Moldau)—Elbe's largest tributary—rises in Austria (Schwarzenberg, Šumava). The Elbe mainstem does not flow through Austria. |
| Poland | Minor border tributaries only | Headwaters of the Ohře (Eger) and Bóbr rise in Poland (Jizera Mts, Karkonosze). The Elbe mainstem does not flow through Poland. |
The Elbe main channel flows only through the Czech Republic and Germany. Austria and Poland contribute tributary headwaters (Vltava, Ohře, Bóbr) but not the mainstem. Many sources oversimplify this.
Water quality dramatically improved since 1990 (post-reunification industrial cleanup). Salmon returned (2000s). But: sediment contamination, low-flow warming, navigation deepening impacts remain challenges. Natura 2000 sites along much of course.
