Lake South Pesteana was formed, starting with 2015, with the cessation of productive activities (lignite mining) in the open pit of the same name. Until now, the remaining gap of the open pit is flooded in a proportion of over 70%, the level being maintained by keeping in operation a part of the dewatering system that served the open pit, in order to protect the nearby railway and households. The main sources of water are aquifers (phreatic and deep-water) intercepted by mining works and to a lesser extent water directly from rainfall or surface runoff. At the moment, a precise destination of the newly formed lake is not established, however being...

Former Lubstów open pit, one of the pits located in the Konin mining area, Poland, with its post-exploitation lake has been selected as one of the main research sites in the RAFF project. The present study discusses complex geological, hydrogeological and morphological features of the study area, it also gives a short overview of the applied reclamation methods and an ongoing process of the post-exploitation lake flooding.

The paper presents a brief summary of the available knowledge on the lake Most, mainly the development of geographical, geological and both hydrological and hydro-geological characteristics of the site. The entire article is divided into sections that contain a description of the original state before surface mining, the history of mining activity impacts in the landscape, the characteristics of the material forming the dump and the ways of its creation. Further sections contain description of the development of the geotechnical and hydro-geological conditions of the site and also a description of the current state of the recovery and reclamation of...
