In 2023, the Ministry of Health included two points of Lago Superiore, the largest of the three basins formed by the river Mincio around Mantova, among the national territory's swimmable locations, where swimming had been prohibited since 1978. On April 1st of the previous year, Mayor Mattia Palazzi signed an ordinance revoking the ban that had been in place since then, once again allowing swimming in Lago Superiore.
On the ministry's portal dedicated to swimming sites, two points on opposite shores of the lake, north and south, are listed as swimmable, where microbiological water analysis samples had been taken over the past four years. The ban on swimming in the lakes of the municipal territory was introduced in 1978 due to dangers related to the presence of certain bacteria.
