The Ecomuseum of the Seasonal lakes of Pivka presents the story of water in the karst world of the Upper Pivka Basin. The area’s unique geological structure, combined with the uneven distribution of precipitation, causes a large fluctuation in the karst groundwater level. As many as seventeen intermittent lakes form in the valley along the high waters. To determine their formation, a special mill wheel must be turned. Individual lake presentations also include locals’ lives in the landscape, where there is sometimes too much and sometimes too little water. Models of the most important living environments, including wet and dry meadows, bushes, forests, and caves, supplement presentations of the Pivka basin’s extremely diverse flora and fauna.
