New ecological solution to improve the lakes capacity by combating the excessively developed vegetation

The paper presents a solution designed and tested hydroelectric lakes, which have the useful volume reduced by 80% since the commissioning. The experimental prototype perfectly ecologic may be applied into hydropower lakes with complex utilization, including water supply for human necessities and cities. At the beginning are mentioned some responsible factors as the climate, hydrological, physical, and chemical for the lake’s eutrophication. The vegetation developed so rapidly, diminishes quickly the water volume of the hydropower lakes, meaning less produced electric energy. Further, are presented the previous solutions tested, without any effect. This new solution, proposed as patent, is realized and tested in the Lake Pangarati. The main steps, challenges, and main solutions, during the utilization, are mentioned. Finally, in images are presented the obtained results, the real differences between shores with and without the barrier utilization. This new ecologically and friendly environment solution, to combat the excessive vegetation has a considerable
efficiency and low costs. The main purpose is to rehabilitate the area and to reestablish the previous environmental conditions, taking into account that these two lakes Pangarati and Vaduri are RAMSAR sites since 2006. Finally, are mentioned some conclusions, acknowledgments, and references.
