The Preajba-Facai lacustrine system is located in the southern part of Craiova municipality and it is distinguished by a high level of originality conferred by both its hydro-geomorphological and biological features. The construction of this series of lakes along the Preajba river began during the Communist times (in the 1970s) with the declared aim of serving as a recreational space for the inhabitants of this municipality. The river springs near Cârcea locality at an altitude of 192 metres and it flows into Craiova channel after 9.6 km, with a source-mouth level difference of 121.1 metres. Chronologically, the number of lakes situated along the Preajba river may vary, according to the analysed cartographic document, from 3 lakes (Military Topographic Maps) to 11 lakes (Topographic Map, 1:25,000). With the development of the area covered by water, the human pressure has increased as a consequence of the intensive development of the surrounding area. This phenomenon gradually led to an involution of the lake surface (25.34 ha in 2014, Google Earth PRO). The aim of this research is to highlight the relational dynamic appearance-evolution-involution suffered by the lakes situated along the Preajba Valley, in correlation with the processes that occurred at the level of the constructed surface and in terms of respecting the status of this protected area of aqua-faunistic interest (The Lacustrine System of Preajba-Facai).
