Lago di Mergozzo

Lago di Mergozzo (En. Lake Mergozzo) is a small sub-alpine lake in northern Italy just to the west of Lago Maggiore and north of Lago d'Orta, at the mouth of the Val d’Ossola in the province of Verbano Cusio Ossola, Piedmont. In ancient times, it was the extreme point of the short northwestern arm of Lago Maggiore, formed by glaciation. However repeated flooding of Maggiore's tributary the Toce deposited sediment which gradually formed a stretch of land which cut off Mergozzo from the larger expanse of water, and from the Toce itself. Today, the settlement of Fondotoce (a frazione of Verbania) stands on this alluvial plain. The small town Mergozzo, which lies at the other end of the lake, gives it its name. The greater part of the lake falls within the commune of Mergozzo, the rest within Verbania. Monte Orfano (790 m) rises from the southwest shore of the lake; the limestone rocks of which it is composed are heavily quarried.
