The project of major repairs of the transport and supply canals "Hromadsky", "105 km", "Zhelyavsky" together with the restoration of four eponymous regulating locks ("Hromadsky", "105 km", "Zhelyavsky", "Skunda") is a strategic infrastructure solution for the recovery of the ecosystem of the Danube Lakes. The main goal of the project is to large-scale restoration of the hydrological connection between the Danube River and inland water bodies, which is currently disrupted due to critical siltation of the channels and the emergency state of the locking mechanisms. Within the framework of the implementation, it is planned to clear the bottom of the channels from perennial silt deposits and aquatic vegetation to return them to the design parameters of depth and width, as well as perform a complex of general construction works on the locks, which includes concrete repair, replacement of worn metal gates and renewal of lifting mechanisms. The main problem that the project solves is the progressive degradation of water bodies: due to the low throughput of the channels, the lakes do not receive enough fresh water, which leads to their shallowing, a rapid increase in mineralization, "blooming" and mass death of fish. In addition to the environmental aspect, the project overcomes the shortage of resources for irrigated agriculture, which is critical for the food security of the region in the face of climate change. The expected results of the project implementation are the full restoration of managed water exchange, the reduction of water salinity in lakes to safe levels, the stabilization of water levels for the needs of agriculture and the fishing industry, as well as ensuring reliable protection of nearby territories from floods due to the proper operation of regulating structures.
