Extremadamente bajo nivel de agua en el este de Croacia: 'Si no fuera por esta presa, Vuka se quedaría sin agua'

Extreme low water levels have been recorded along the eastern coast of Croatia, with experts warning that such extreme conditions are becoming increasingly common rather than rare. The situation has prompted urgent measures to mitigate the effects of drought on local rivers, particularly the Danube and the Drava. According to Željko Kovačević, director of the Water Management Department of Croatian Waters for the Danube and Lower Drava, the past decade has witnessed more frequent and prolonged periods of low water levels approaching extremes. These occurrences, while not entirely unexpected, are happening too often and at times when they are least anticipated. Low water levels are appearing when high ones were expected, and floods are occurring during periods of low water. This shift in river regimes is evident in recent years, according to Kovačević. The changes in river dynamics are attributed to climate patterns that have become more unpredictable. In response to these challenges, workers from Croatian Waters have installed a rubber dam at the mouth of the Vuka River into the Danube. This measure aims to alleviate the impacts of the drought and preserve aquatic life within the river system. Without this dam, the Vuka would effectively run dry, threatening the ecosystem. The structure helps maintain a biological minimum level necessary for sustaining life in the river. During periods of high water levels in the Danube, the dam is lowered to allow fish to migrate upstream into the Vuka for spawning purposes. Once this process is complete, the dam is raised again to ensure continued water flow and ecological balance. The installation of the rubber dam reflects broader efforts to adapt to changing environmental conditions. As climate change continues to influence weather patterns, the frequency of extreme hydrological events is expected to rise. This necessitates proactive management strategies to protect both human infrastructure and natural ecosystems. Authorities are monitoring the situation closely and adjusting their interventions based on real-time data and forecasts. The goal is to find a sustainable balance between maintaining adequate water levels for ecological health and ensuring the functionality of water-related infrastructure. Experts emphasize that the current situation is part of a larger trend. Climate models predict that such extreme weather events will become more frequent in the coming decades. This underscores the need for long-term planning and investment in resilient water management systems. Local communities and industries reliant on stable water supplies are being advised to prepare for potential disruptions. Emergency protocols are being reviewed and updated to address the growing risks associated with both droughts and floods. In addition to physical interventions like the rubber dam, there is a focus on improving water conservation practices and enhancing public awareness about the importance of sustainable resource use. Educational campaigns are underway to inform residents about how individual actions can contribute to reducing strain on water resources. These initiatives aim to foster a collective effort towards preserving water quality and availability for future generations. Authorities remain vigilant as they monitor ongoing developments and assess the effectiveness of current mitigation strategies. They are working closely with meteorological services to stay informed about upcoming weather patterns and adjust their responses accordingly. The ultimate objective is to safeguard the region's water resources against the increasing threats posed by climate variability. Continued research and collaboration among scientists, policymakers, and local stakeholders are essential to developing comprehensive solutions that address both immediate concerns and long-term sustainability goals.
