Lago di Mezzo is the smallest among three lakes in Mantua, both in terms of surface area and volume, but it reaches the greatest depth, 15 meters. It is regulated at an altitude of 15 meters above sea level, like Lake Inferiore, from which it is separated by a dam and the existing San Giorgio bridge, already present in 1199. This was a covered bridge with a drawbridge, but after the disappearance of the covering in the early decades of the 20th century, its arches were buried.
In the waters of Lake di Mezzo, you can find a native rarity, the Trigol (Trapa natans), also called water chestnut, due to its edible fruits that are collected in late autumn.
