Paraná River rising due to El Niño phenomenon

The Paraná River is experiencing a significant rise in water levels, driven by a strong El Niño event. This natural cycle is expected to reach heights not seen in over a decade, helping to regenerate the river delta ecosystem which has suffered from successive droughts, fires, and human interventions since 2019.

In regions such as Monte Vera and Santa Fe, the rising water has already begun to advance onto coastal areas and cause accumulations of floating vegetation, such as water hyacinths, in Laguna Setúbal. This buildup may create challenges for navigation and vessel access in certain sectors.

The National Water Institute (INA) projects an upward trend for the river levels in the Santa Fe and Paraná stretches. While recent estimates have been revised slightly downward compared to previous forecasts, the river is expected to continue rising, with levels in the port of Santa Fe projected to reach approximately 4.92 meters by early November.
