Lake Maggiore rises: +15 cm, environmental concerns

Contesto

In brief - Lake Maggiore rises to +1.40 meters - +15 cm above the current threshold - Concerns for tourist spots ## Key facts - What: Experimental rise in the lake's maximum level - When: From May 1, 2026 - Where: Lake Maggiore (Switzerland/Italy) - Who: Po River Basin Authority (ADBPO) - Amount: +15 cm above the current threshold The ADBPO has announced the experimental rise of the maximum level of Lake Maggiore to +1.40 meters above the zero hydrometric level of Sesto Calende. This 15-centimeter increase from the current threshold of +1.25 meters has been decided to meet the agricultural and hydroelectric needs of the Po Valley. The Italian authority, under the supervision of the Ministry of the Environment and Energy Security, manages the waters of the Po River basin and sets the lake level. The new level will be controlled by the Ticino Consortium through the Miorina dam in Golasecca (Varese). ### Effects on the environment and tourism The rise in the lake level could have significant effects on the tourist spots along its shores, both in Switzerland and Italy. A 15-centimeter increase in the water level could reduce the availability of beaches and recreational areas. Additionally, the lake ecosystems could be affected, especially during the critical reproductive period. ### Seasonal modulation The ADBPO has introduced a new seasonal regulation divided into four periods: - +1.50 meters in winter, between November 15 and February 28 - +1.00 meters in spring, between March 1 and April 15 - +1.35 meters between April 16 and July 31, raiseable to +1.40 meters in case of water stress - +1.00 meters from August 1 to November 14 ### Future projections The ADBPO also mentioned the possibility of reaching +1.50 meters in the future, in line with the climate projections...

Implications for cross-border workers The rise of Lake Maggiore could have implications for cross-border workers living and working in the surrounding areas. Tourist destinations, which are an important source of income for many cross-border workers, could see a decline in visitors due to the reduction of beaches and recreational areas. This could directly impact the services and tourism sector, which employs many cross-border workers. ### Impact on agriculture and hydropower industry The rise in the lake's level could have a positive impact on agriculture and the hydropower industry. Approximately 170,000 hectares of agricultural land in the Po Valley directly depend on the lake's waters. Additionally, the hydropower industry downstream of the basin produces about 500 gigawatt-hours per year, equivalent to the electricity needs of nearly 200,000 families. The rise in the lake's level could increase hydropower production and improve water security for agriculture. ### Effects on the environment The rise of the lake could have negative effects on lacustrine ecosystems. Ecosystems could be influenced, especially during the critical reproductive period. Furthermore, the rise in the lake's level could impact the Piedmontese natural reserves and the Bolle di Magadino, protected areas of great ecological value. ### Comparison with the previous situation Before 2007, the lake's maximum level was +1.5 meters in winter and +1.0 meters in summer. In 2007, the Italian Government granted an exemption to increase the summer level to +1.25 meters. In 2015, ADBPO initiated an experiment that led to the current level of +1.25 meters. The rise to +1.40 meters represents a further step towards the goal of +1.50 meters, which has been discussed for years. ### Future scenarios If the r...

What to do now Cross-border workers living and working in the areas surrounding Lake Maggiore should closely monitor developments related to the lake's water level rise. It's important to be aware of potential impacts on the environment and tourism, which could directly affect their work and economic activities. ### Procedure for reporting environmental impacts If negative environmental impacts are noticed due to the lake's water level rise, these effects can be reported to the competent authorities. In Switzerland, you can contact the Ticino Consortium, while in Italy, you can turn to the ADBPO or local authorities. ### Useful tools To monitor developments related to the lake's water level rise, you can use tools like the lake level calculator or the risk area mapper. These tools can provide updated information on the lake level and potentially affected areas. ### Conclusion The rise of Lake Maggiore to +1.40 meters represents an important decision that could have a significant impact on the environment, tourism, and local economy. It is crucial to closely monitor developments and report any negative impacts to the competent authorities. Using tools like the lake level calculator can help better understand the implications of this decision. Source: tvsvizzera.it
