Lake Maggiore: Italy-Switzerland deal for more spring water

Contesto

In brief - Maximum level of Lake Maggiore raised to 1.40 meters - Italy-Switzerland agreement to combat water crisis - More reserves for summer irrigation ## Key facts - What: Raising the maximum level of Lake Maggiore - When: Decision made on April 29, 2026 - Where: Lake Maggiore, Italy-Switzerland border - Who: Po River Basin Authority, Piedmont and Lombardy Regions, Ticino Consortium, Italy-Switzerland Bilateral Body - Amount: Up to 30 million cubic meters of additional water available After ten years of experimentation, the raising of the maximum regulation level of Lake Maggiore to 1.40 meters above the zero hydrometric level of Sesto Calende becomes a reality. A decision that directly affects the province of Varese, bathed by both Lake Maggiore and the Ticino River, and could guarantee between 20 and 30 million additional cubic meters of water available during the driest periods — with overall volumes that can reach up to five times higher during the irrigation season. The decision was made on April 29 at the end of the Permanent Institutional Conference, the result of an agreement coordinated by the Po River Basin Authority together with the Piedmont and Lombardy Regions, the Ticino Consortium, the Italy-Switzerland Bilateral Body, and numerous stakeholders. The maximum allowed level will rise from the current 1.25 meters to a range between 1.35 and 1.40 meters, with the possibility of reaching the highest value in case of low snow cover in the Alps, a condition that is becoming increasingly frequent with climate change. The logic is to accumulate water in the spring season to make it available in the summer months, when irrigation demand is higher and rainfall is scarce. For the Varesotto territory, the reflection is direct: the Ticino, which originates from...

Dettagli operativi

The agreement reached between Italy and Switzerland to raise the maximum level of Lake Maggiore represents a significant step in the management of water resources, especially in a context of climate change and increasing water crisis. This agreement not only increases the availability of water for summer irrigation but also has important implications for tourism and swimming along the lake's shores. ### Implications for Agriculture Raising the lake level by up to 1.40 meters allows for the accumulation of larger amounts of water during spring, making it available in the summer months when irrigation demand is highest. This is particularly important for the rice fields of Lomellina, the Milanese plain, and the lower Pavese area, which represent Europe's first rice-growing sector. Greater water reserves mean greater security for crops during drought periods, reducing the risk of economic losses for farmers. ### Impact on Tourism and Swimming Raising the lake level could also have an impact on tourism and swimming. The Piedmont assessors have guaranteed careful monitoring of the areas designated for these activities, ensuring that the changes do not compromise the safety and quality of tourist experiences. This is particularly relevant for the Varese shores of Lake Maggiore, which attract numerous visitors every year. ### Cross-Border Cooperation The agreement also represents an example of effective cross-border cooperation. More than half of Lake Maggiore is Swiss, and any modification to its regulation requires the involvement of the Swiss Confederation. The fact that the agreement has been reached demonstrates the ability of the two nations to work together to address common challenges, such as water resource management and adaptation to climate change. ### Concl...
