The paper describes the most common methods used for reclaiming water reservoirs. It reviews the most important publications from recent years, outlines the historical background to the problem in question, and provides some examples of the practical applications of each method. The reclamation methods were characterised in detail, taking into account general assumptions, usability, efficiency and cost. Reclamation should be considered as the last resort and employed in cases when earlier protective activities within a catchment have not produced the desired effect. For some strongly eutrophic reservoirs, however, such a measure is necessary in order to achieve improvement in water quality. Reclamation activities should always be preceded by a thorough, interdisciplinary examination of the catchment and the reservoir itself.
