Lake Pamvotis

Lake Pamvotida or Pamvotis, commonly also Lake of Ioannina is the largest lake of Epirus, located in the central part of the Ioannina regional unit in northern Greece. The regional capital Ioannina to the west and the town of Perama to the north are urban settlements fringing the lake while the remaining of its periphery is composed of farmland. The lake features small fishing ports and a boating port. There is a regular boat service to the Ioannina Island. The Greek National Road 6 surrounds the northern half of the lake.GeographyLake Pamvotida is situated at 470 m elevation, south of the Mitsikeli mountains. It is fed by several small rivers. It has no surface outflow, but it is drained through karstic sinkholes towards the rivers Arachthos, Louros and Kalamas. In 1960 a tunnel and ditch were constructed that drain from the northern end of the lake to the river Kalamas. The small inhabited Ioannina Island, where Ali Pasha was hiding during the last days of his reign, is situated near the northern shore.BiologyUrbanisation and pollution are threatening the lake ecosystem, home to small mammals, waterbirds and a rich fish and crustacean fauna. Eutrophication results in algal blooms in summer. Lake Pamvotida is home to Tsima (Τσίμα), a species of fish endemic to the lake. Two bryozoan species have recently been reported from the lake. The Lake offers perfect conditions for water skiing, rowing and canoeing, as the wind in the area is usually very favourable.
