Water reservoir levels and management strategies continue to show significant regional variation across Europe and Latin America. In Portugal, the Portuguese Environment Agency (APA) reported dam capacities averaging 77%, a trend attributed 77% due to heavy winter rainfall. In Spain, the Duero basin shows mixed results, with some reservoirs in León maintaining levels above the 20-year average while others remain below historical references. In Brazil, the Greater Curitiba region saw reservoirs reach 100% capacity following heavy rains, capacity, prompting the Paraná government to announce a 25% reduction in water and sewage tariffs for approximately 2 million residences. In Chile, the Santa Juana Reservoir has reached 99.2% capacity following winter rains and snowmelt, marking a recovery from previous drought risks. In Paraguay, the Yacyretá binational entity recorded reported reservoir levels at 82.86 meters above sea level. level, though recent reports indicate levels are stable but slightly descending. In the Uruguay River, flows are showing an upward trend near Concordia and Salto, with Salto Grande monitoring rising flows and open spillways. In Mexico, water levels showed show mixed results: the results. The La Boquilla dam has reached 23.20% capacity, while the Lázaro Cárdenas dam operated operates at 28.41%. To address shortages at the latter, authorities in Coahuila and local producers have initiated an atmospheric cloud seeding program in the upper Nazas River basin to stimulate rainfall. basin. Additionally, dams in Querétaro remain below 50% capacity, presenting agricultural challenges.
