Coordinates: 39°22′N 21°55′E Karditsa (1) Plastiras Lake (3)
The main rivers are Tavropos (Megdovas) in the south, the Pineios in the north, and the Enipeas in the east. The Plastiras Dam and Lake Plastiras, located to the west of the city of Karditsa, supply water to the plains and the central part of Greece.
Located in south-western Thessaly, it is primarily an agricultural area. Farmlands dominate the central and the eastern part, which belongs to the Thessalian Plain. The western and southern part of the peripheral unit is mountainous, notably the Pindus mountains. The Agrafa region, straddling the border with Evrytania, is well known for its resistance against Ottoman rule and its harsh landscape.
Lake Plastiras also called Tavropos Reservoir is an artificial lake fed by Tavropos (Megdovas) river, located near the city of Karditsa.
The lake is named after the Greek general and politician Nikolaos Plastiras, who was the first to visualize the construction of an artificial lake in the area. The idea of building a reservoir in the area was allegedly first conceived by general Nikolaos Plastiras who, in 1925, was visiting his hometown in the area. During this time the whole prefecture was devastated by a major flood of the river Tavropos. He put pressure to the Minister of Agriculture, who put together a team to study the case by 1929. The following years till the Second World War the idea was met with opposition by politicians.
After the war, the idea was revived by Plastiras as he was proclaimed Prime Minister. The (then newly formed) Power Corporation adopted the project as part of their effort to electrify the country. An international contest was held in 1953 that was won by the French Omniun Lyonnais. The building of the dam started on December 14, 1955. On October 30, 1960 the dam was officially inaugurated, although the flooding may have started as early as the last months of 1959.
Today the lake holds up to 400 million cubic meters of fresh water. It is used for irrigation and as a power source of a hydroelectric plant, but also as the main water source to the city of Karditsa. Due to its altitude (one of the highest in Europe) the Tavropos Reservoir is a popular tourist resort in Greece, as the formed landscape is quite unique.
