Lake Plastiras. Also known as the Tavropos Reservoir, it is a large artificial lake in central Greece. Created by the damming of the Tavropos River, it is situated in the Agrafa mountains within the Karditsa (regional unit) of the Thessaly region. The lake is named after the Greek general and statesman Nikolaos Plastiras, who envisioned the project to control flooding and provide resources for the arid plains below.

Geography and Hydrology

The lake is nestled in the rugged terrain of the Pindus mountain range, specifically within the Agrafa area, at an altitude of approximately 800 meters. Its primary hydrological input is the Tavropos River, which is a tributary of the larger Acheloos River system. The reservoir's creation significantly altered the local hydrology, regulating the flow of the Tavropos and providing a steady water supply to the agricultural lands of the Thessalian Plain. The surrounding peaks, such as those in the Nevropoli Agrafon region, contribute to its catchment area, creating a dramatic landscape where water from seasonal streams and snowmelt feeds the lake.

History and Construction

The concept for damming the Tavropos River was championed in the 1920s by General Nikolaos Plastiras, a native of the region, following devastating floods in the city of Karditsa. The project aimed to mitigate flooding, generate hydroelectric power, and irrigate the fertile but dry plains of Thessaly. Construction of the dam began in 1958 and was completed in 1962, a project overseen by the Greek state with technical assistance from international engineering firms. The creation of the reservoir led to the submersion of the old bridge of Mouzaki and required the relocation of several small communities, fundamentally changing the human geography of the area.

Ecology and Environment

The lake and its surrounding forests have developed into an important ecological niche within the National Park of Agrafa. The reservoir's waters support populations of fish such as rainbow trout and carp, which were introduced for sport fishing. The surrounding mixed forests of Greek fir, black pine, and various oak species provide habitat for wildlife including roe deer, brown bear, and numerous bird species like the golden eagle. Environmental management focuses on maintaining water quality for downstream use and protecting the riparian zones from erosion, with oversight from agencies like the Hellenic Ministry of Environment and Energy.

Tourism and Recreation

The area has become a prominent four-season tourism destination, often marketed as "Little Switzerland" due to its alpine scenery. Key activities include hiking on trails through the Agrafa forests, mountain biking, and horse riding. In winter, the nearby Pertouli ski resort attracts visitors, while the lake itself is popular for kayaking, fishing, and boat tours. The picturesque villages around its shores, such as Morfovouni and Kastania (Karditsa), offer traditional guesthouses and tavernas, with local festivals like those in Meskounti drawing cultural tourists.

Dam and Infrastructure

The Plastiras Dam is a straight gravity dam constructed from concrete, standing 83 meters high and 220 meters long. It was a significant feat of engineering for mid-20th century Greece, designed primarily for irrigation and secondarily for hydroelectric power generation, with its output fed into the national grid managed by the Public Power Corporation. The dam's infrastructure includes controlled spillways and outlet works that regulate releases into the lower Tavropos River, ensuring water for the extensive irrigation networks serving crops in the Thessalian Plain near cities like Karditsa and Trikala.
