This study is part of a larger analysis of the changes of the cultural landscapes in the Hârtibaciu River Basin. Regarding the lacustrine landscape present in the village of Brădeni, we encounter massive changes in the landscape. The lakes were edified in the communist period with two main purposes: flooding prevention and pisciculture. In the last quarter-century the lakes administrations ignored the cleaning activities and the cutting of the water vegetation consisting mainly from reed and cattail, so that the lakes are at risk of full coverage with this species of plants. The progress of the degradation is analysed on different Landsat images. The conclusions suggest some solutions for an economic development with the harvesting of reed in concordance with the preservation of the species as part of Natura 2000 site.
