The commission, established in 1998, deals with the whole Danube river basin, which includes tributaries and the groundwater resources. Its goal is to implement the Danube River Protection Convention by promoting and coordinating sustainable and equitable water management, including conservation, improvement and rational use of waters and the implementation of the EU Water Framework Directive.
