Lake Piva (Пивско језеро| Pivsko јezero) is a reservoir in Montenegro. It is located in the northwest part of the country, in Plužine Municipality. The surface of the lake is 12.5 km², the length is 45 km, and the maximum depth is 188 m. The elevation is 675 m above sea level.
The artificial lake is the result of the construction of Mratinje Dam on the Piva River.[1] On the bottom of the lake there is the old town Plužine; Piva Monastery was also there, but it has been relocated. The new location of the monastery is 8 km from Plužine, and 3.5 km away from the original location of the monastery. The relocation has started in 1969 and finished in 1982.[2]
