Lake Bracciano, originally also called Lake Sabatino (Latin: Lacus Sabatinus), is a lake that fills a depression of volcanic and tectonic origin, located north of Rome and surrounded to the north by the Sabatini Mountains.
Its surface area of 56.5 km² makes it the eighth largest lake in Italy (the third largest in Central Italy after Lake Trasimeno and Lake Bolsena). Its maximum depth, now down to 160 m in turn, makes it the sixth deepest lake in Italy (the second deepest in Central Italy after Lake Albano). The lake has no islands and has a small emissary, the Arrone river, which originates on the south-eastern coast and flows into the Tyrrhenian Sea at Maccarese. Two kilometres east of the lake is the smallest lake of Martignano, also of volcanic origin.
On the shores of the lake are the three towns of Bracciano, on the western side, Anguillara Sabazia, on the south-eastern side, and Trevignano Romano, on the northern side. A stretch of the eastern shore of the lake is finally administratively part of Roma Capitale.
Together with the lake of Martignano.
