1.2 Data sources, geographical coverage, and methodology

This report is compiled from information on the status of European surface water and groundwater bodies as reported by the EU Member States into the Water Information System for Europe (WISE). In summer 2017, 25 Member States had reported into WISE. The WISE-WFD database includes data from the first and second RBMPs. The reporting of WFD data is based on the CIS Reporting Guidance, which has been revised in 2016[1].

The implementation of the WFD has resulted in the designation of 180 RBDs across the EU, and 31 international RBDs. RBMPs have been produced for all the RBDs. Each of the RBMPs consists of many different documents, maps and datasets. The main RBMP document that often is 200-300 pages long provides detailed information on status and pressures affecting the designated water bodies, monitoring programmes and the Programme of Measures to be implemented during the new management cycle. In addition, RBMPs often include several appendixes and in some cases, Member States have established interactive map services or information systems to provide detailed information for the individual water bodies.

This report only presents key results, while more detailed WFD results are presented in an interactive tool in WISE. The following chapters include small text boxes with links to more detailed information (see examples below)
