Executive Agency for Exploration and Maintenance of the Danube River
The Executive Agency for Exploration and Maintenance of the Danube River (EAEMDR) of Bulgaria was established as an organization in 1935 under the name Danube Hydrographical Service within the structure of the Ministry of Railways, Post Offices and Telegraphs. The headquarters were situated in the city of Lom and the responsibilities of the Service were related to the maintenance of the waterway, creation of maps of the Danube River, conduction of hydro meteorological surveys in the Bulgarian section of the river.

History
The Danube Hydrographical Service was established in 1935 to maintain the Bulgarian section of the Danube. In 1949, after the ratification of the “Convention for the sailing regime on the Danube River”, the Danube Hydrographical Service passed over to the Ministry of Defense – Danube Fleet. 

Four years later the service was reinstated as a part of the Ministry of Railways, Post Offices and Telegraphs, and the Navigational Waterway Office was established in Ruse. In the year 1955 the organization passed over under the structure of the Bulgarian River Fleet and in the next year the Council of Ministers adopted a decree, by the force of which the Navigational Waterway Office was restructured into the “Administration for the Maintenance of the Navigational Waterway and Exploration of the Danube River” within the Ministry of Transport, Information technology and communications. 

In December 1999 the Administration was transformed into the Executive Agency for Exploration and Maintenance of the Danube River.
