The Survey on the Implementation of Measures of the Programme "Rhine 2020" until 2005 gave evidence of first success. As the Survey 2012 shows, several national measures implementing the EC Water Framework Directive have considerably enhanced this success. Notable improvements have been achieved, even though, in one sector, much remains to be done before the target set for 2020 will be attained. Further efforts are required, e.g. concerning an increased diversity of river banks.
