El Niño rains force Itaipú and Yacyretá dams to open gates on Paraná River

Heavy El Niño-driven rainfall has raised the Paraná River, forcing the Itaipú and Yacyretá hydroelectric dams to open their main reservoir gates. The move is a flood-control measure to manage water levels, but it also signals potential downstream flooding and disruptions to hydropower generation. The situation is developing as rainfall continues.
