A new method (MHR) of hydromorphological monitoring of artificial water bodies is presented. The total length of artificial water bodies in Poland is about 2000 km, which indicates the need to use a simplified method of assessment in relation to the natural or heavily modified water bodies. The assessment of the ecological potential of the water body has been based on four elements, 19 features and 34 attributes which form a hierarchical assessment system. Scoring of the features is based on the characteristic of attributes and involves only 10 features and 20 attributes. This is caused by their specificity. The method of the assessment is illustrated by the protocol. The ecological potential is assessed within four classes. The MHR method allows to identify the parts of the water body that do not score a good ecological potential and indicate the cause. It allows for the implementation of the Water Framework Directive.
