Navigation

The Danube Commission is concerned with the maintenance and improvement of the river's navigation conditions. It was established in 1948 by seven countries bordering the river. Members include representatives from Austria, Bulgaria, Croatia, Germany, Hungary, Moldova, Slovakia, Romania, Russia, Ukraine, and Serbia; it meets regularly twice a year. It also convenes groups of experts to consider items provided for in the commission's working plans. The commission dates to the Paris Conferences of 1856 and 1921, which established for the first time an international regime to safeguard free navigation on the Danube. Today the Commission include riparian and non-riparian states.

Ancient cultural perspectives of the lower Danube

Part of the rivers Danubius or Istros was also known as (together with the Black Sea) the ''Okeanos'' in ancient times, being called the ''Okeanos Potamos'' (Okeanos River). The lower Danube was also called the ''Keras Okeanoio'' (Gulf or Horn of Okeanos) in the ''Argonautica'' by Apollonius Rhodos (Argon. IV. 282). At the end of the ''Okeanos Potamos'', is the holy island of Alba (Leuke, Pytho Nisi, Isle of Snakes), sacred to the Pelasgian (and later, Greek) Apollo, greeting the sun rising in the east. Hecateus Abderitas refers to Apollo's island from the region of the Hyperboreans, in the Okeanos. It was on Leuke, in one version of his legend, that the hero Achilles was buried (to this day, one of the mouths of the Danube is called Chilia). Old Romanian folk songs recount a white monastery on a white island with nine priests.''Dacia Preistorica''

and Passau also use some water from the Danube. In Austria and Hungary, most water is drawn from ground and spring sources, and only in rare cases is water from the Danube used. Most states also find it too difficult to clean the water because of extensive pollution; only parts of Romania where the water is cleaner still obtain drinking water from the Danube on a regular basis.


Navigation and transport

In the 19th century, the Danube was an important waterway but was, as ''The Times'' of London put it, "annually swept by ice that will lift a large ship out of the water or cut her in two as if she were a carrot." Today, as "Corridor VII" of the

The Danube has been partly canalized in Germany (5 locks) and Austria (10 locks). Proposals to build a number of new locks to improve navigation have not progressed, due in part to environmental concerns. Downstream from the Freudenau locks in Vienna, canalization of the Danube was limited to the Gabčíkovo dam and locks near Bratislava and the two double Iron Gate locks in the border stretch of the Danube between Serbia and Romania.

Zillen are still used today for fishing, ferrying, and other transport of goods and people in this area.


Fishing

The importance of fishing on the Danube, which was critical in the

, has declined dramatically. Some fishermen are still active at certain points on the river, and the Danube Delta still has an important industry. However, some of the river's resources have been managed in an environmentally unsustainable manner in the past, leading to damage by pollution, alterations to the channel, and major infrastructure development, including large hydropower dams. The sturgeon stocks associated with the Danube River basin have, over the centuries, formed the basis of a large and significant commercial fishery, renowned throughout the world. The construction of the dams, besides overfishing and river pollution, has a significant role in sturgeon population decline because it creates a barrier for fish migratory species that usually spawn in the upper parts of the river. The spawning areas of migratory fishes species has been dramatically reduced by the construction of hydropower and navigation systems at Iron Gates I (1974) and Iron Gates II (1984) The initial design of these dams has not included any fish passage facility. The possibility of building a man-made fish pass enabling migration for fish species including the sturgeon, is currently under review by projects such as We Pass. The Upper Danube

In medieval Regensburg, with its maintained old town, stone bridge and

, the university city of Krems and the cosmopolitan city of Vienna. Before the Route of Emperors and Kings ends, you pass Bratislava and Budapest, the latter of which was seen as the twin town of Vienna during the times of the Austro-Hungarian Empire. Since ancient Roman times, famous emperors and their retinue traveled on and along the Danube and used the river for travel and transportation. While traveling on the mainland was quite exhausting, most people preferred to travel by ship on the Danube. So the Route of Emperors and Kings was the setting for many important historical events, which characterize the Danube up until today. The route got its name from the Holy Roman Emperor Frederick I of Barbarossa and the
