Jezero Jižní Pesteana
Jezero Jižní Pesteana vzniklo počátkem roku 2015 ukončením produktivních činností (těžba hnědého uhlí) ve stejnojmenném povrchovém dolu. Doposud je zaplaveno přes 70% původní části povrchového dolu, přičemž výška hladiny je udržována provozem části odvodňovacího systému, který sloužil povrchovému dolu tak, aby byla chráněna blízká železnice a domácnosti. Hlavními zdroji vody jsou zvodně (freatické a hlubinné) přerušené důlními pracemi a v menší míře voda přímo ze srážek nebo povrchového odtoku. V současné době není stanoven přesný účel nově vzniklého jezera, avšak v úvahu se berou různé možnosti: rekreační jezero, rybolovné jezero, zavlažovací nádrž nebo jejich kombinace.

Lake South Pesteana
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 taken into account different options: recreational lake, fish lake, irrigation tank or combinations between them.
