This article presents the concept of the methodology for assessing the implementation of programmes of measures adopted in the State Water and Environmental Programme, and, in consequence, in the framework of the first water management plans for river basin districts in Poland, as approved by the Council of Ministers on 22nd February, 2011, and published in the official journals. The scope of work in the methodology concept primarily concerns two basic analyses: assessment of the accomplishment of programmes of measures with regard to the degree of their accomplishment, and assessment of the effectiveness of scheduled programmes of measures. The level of accomplishment should be understood as the quantitative status of progress of particular measures, whereas effectiveness means their direct or indirect impact on the achievement of environmental goals of the Water Framework Directive. For this purpose, for some of the measures databases and reports existing in institutions responsible for the performance of measures indicated in the SWEP were used. For the rest of the measures, the survey method was used. For the purpose of the surveying process, the preparation of appropriate matrixes with measures marked for institutions, and also of email address databases, were proposed. Also, identifiers serving to link answers with specific areas on maps that trace measures were proposed. The present and forecast situation concerning reporting in the scope of the WFD and other tasks connected with it in the field of environmental protection leads to the conclusion that the coordination of reporting at the state level and the improvement of the flow of information between interested institutions is necessary.
