Lake Pamvotida, Lake in Epirus Region, Greece.

Lake Pamvotida is the largest lake in Epirus, lying at 470 m south of the Mitsikeli mountains, about 7.9 km long and up to 11 m deep. Ioannina fringes its western shore and Perama its northern shore; the rest of the periphery is farmland. The inhabited island of Ioannina sits near the northern shore, with the monastery of Agios Panteleimon where Ali Pasha was killed in 1822.

Lake Pamvotida formed part of the landscape of Ioannina from early times; the lake is dated to around 10,000 BC. In 1822 Ali Pasha was killed in the monastery of Agios Panteleimon on the island, where he had taken refuge during the last days of his rule. In 1960 a tunnel and ditch were built to drain the northern end of the lake toward the Kalamas river.

The name Pamvotis comes from ancient Greek and means "she who feeds everyone". A well-known folk song claims that a thousand talents of sugar were thrown into the lake to sweeten its water for Kyra Frosyni; the water is in fact naturally fresh. The lake is linked to the legends of Kyra Frosyni and Dovrahan, and its eels and crayfish are locally famous.

The lake is easily reached by the national road that runs through the region, and the shoreline is accessible from several points. Boats depart regularly from various locations along the shore for those wanting to visit the central island.

Lake Pamvotida has no surface outflow: its water seeps through karstic sinkholes toward the Arachthos, Louros and Kalamas rivers. Since 1960 a tunnel and ditch also drain the northern end into the Kalamas. The lake holds Tsima, a fish found nowhere else.
