In Kazakhstan, it is planned to build a large-scale mudflow protection complex in the Turgen River basin, the initiative for which was presented to the Minister of Emergency Situations Chingis Arinov. The project involves not only the construction of a mudflow dam, but also a hydroelectric power station, as well as an observation deck for tourists. Such an integrated approach, according to the project developers, should ensure the protection of the population and infrastructure from destructive mudflows, while simultaneously creating new sources of electricity and promoting the development of the region’s tourism potential.
Minister Arinov noted the strategic importance of the facility, emphasizing the need to stay ahead of natural disasters. «Turgen – one of the priority areas where there is no mudflow protection infrastructure. And a very important point is that in addition to the direct protection function, this project will work for the development of the region energetically, socially and economically», he said. However, despite the claimed benefits, such a large-scale intervention in the mountain ecosystem raises certain concerns regarding its long-term environmental consequences, which remain insufficiently clarified at the moment.
The Turgen River basin is characterized as a Category I mudflow hazard zone. Its upper reaches contain 48 glaciers and 20 moraine and glacial lakes, of which six are recognized as breakthrough lakes. The lack of any mudflow protection structures currently makes the area, including infrastructure and tourist facilities along the riverbeds, extremely vulnerable. It is expected that the implementation of the project will significantly increase the level of security and bring economic benefits to the region.
Construction is expected to be financed through private investment, which will reduce the burden on the state budget. However, despite the obvious need for protection from mudflows, the construction of a dam and hydroelectric power station on a mountain river will inevitably affect the local flora and fauna, water regime and landscape. Questions about the degree of this influence, the environmental assessment carried out and measures to minimize possible damage to the natural environment of the Turgen Gorge require more detailed and public coverage.
