Lake Coghinas in Sardinia

About 15 km downstream from Lake Casteldoria, the water from the Coghinas river flows into Lake Coghinas, feeding one of the largest basins in Sardinia. The dam was originally built in the 1920s to produce hydroelectric power, but such is its capacity that it can also cater for the farming and grazing needs of the surrounding areas as well as the water needs of the various, growing towns that are located near to the river. The Tula and Erula territories also play an important role in producing electricity from wind power: on 3 April 2004, the new Sa Turrina Manna wind farm was opened. The landscape, the pre-existing activities and the natural context were all key factors in the creation of this plant. As such, water and wind come together in the Montacuto area to provide power generated using renewable sources (namely, sun and water). In total, enough electricity is produced for about 40,000 families.

Lake Coghinas

Lake Coghinas has a capacity of 254 million m3 of water. It was created by the barrage built across the Muzzone gap on the Coghinas river and now lies in both the Tula and Erula municipalities. The presence of these industrial plants does not, though, diminish the natural beauty of this lovely land where lush vegetation runs along the riverbanks and the slopes around the lake are covered with super cork tree groves that provide shelter and a stopover point for numerous migratory birds. The Coghinas river is the largest watercourse in northern Sardinia and it is fed by a vast rain-collecting basin that receives the water which seeps off the Mt Limbara massif.
The origins of the name are also interesting: the hot springs, which rise to the surface on the Casteldoria plateau, gave the river its Latin name, Thermus; in a way, this name has been maintained in the Sardinian language, since coghina means kitchen. In addition, since the early 1990s, Lake Coghinas has become a popular spot for rowing and is also the site of the traditional Sardinian championships in this discipline.

Sa Turrina Manna

The very modern wind farm in the Tula and Erula municipalities is one of the latest achievements in Enel’s ongoing quest to use sustainable sources to produce electricity. It has 28 wind turbines. In total, these are capable of producing about 24 MW, which translates into enough power for about 20,000 families. It also means that 33,000 tons of carbon dioxide is not released into the atmosphere every year. The plant was also created with great care for the surrounding environment: the wind turbines were placed on the firebreak section of the forest area using already existing tracks, paths and forestry roads.
The material that was initially excavated for the foundations was then re-used to ensure the typical shades and colours of the area remained. In addition, tall trees that are native to the area were planted. Access to the wind farm, both from Tula and Erula, was improved, thus making it easier to get around. In the sections of greatest natural interest, observation hides were built. The wind farm overlooks the hydroelectric basin on the Coghinas.

How to get there

Lake Coghinas is linked to Tempio Pausania (25 km) by the SS392 road; it is also touched by the SS597 Sassari-Olbia, along which, just a short distance from Oschiri, the road branches off for Tula; go through the village and after another 5 km, just after a bridge, you will see on the right a road, unpaved but in excellent condition, that leads to the sailing centre on the edge of the lake.
