![Lavu di Sampolu](https://upload.wikimedia.org/wikipedia/commons/a/ae/Lavu_di_Sampolu.JPG)
The
Lac de Sampolo, or Réservoir de Sampolo, is formed by the Barrage du Sampolo, which dams the Fiumorbo river below the village of Sampolo.
The dam was built between 1987 and 1991 and went into service in 1992.
The concrete
gravity dam is owned by
Électricité de France (EDF) and is used for hydroelectricity and irrigation.
It is high and long, with a crest elevation of above sea level.
The dam holds of water.
It has a surface area of and a catchment area of .
The dam is checked regularly to confirm safety.
Variations in the flow of the river downstream of the dams are controlled.
Below the site is another dam, the Barrage de Trévadine, where the river emerges onto the coastal plain.
The Barrage de Trévadine came into service in 1991 and is also owned by EDF.
It provides hydroelectricty and irrigation water.
It is a concrete gravity dam high and has a crest length of .
The crest is at an altitude of .
The reservoir covers and holds of water.
The catchment area is .

Above and below the Sampolo dam the river has cut two series of rocky gorges.
A small pool between the two has now been covered by the reservoir.
The upper gorge, the Défilé des Strette, is less dramatic than the lower Défilé de l’Inzecca.
The northern side of the Défilé de l’Inzecca is a Natura 2000 site.
The Inzecca gorge has unique geological and floristic aspects found nowhere else in Corsica or France.
The Forets du Fiumorbu is classified as a ''
'' (ZNIEFF).
This area overlooks the eastern coastal plain at Ghisonaccia.
It encompasses the Territorial Forest of Fiumorbu, the Territorial Forest of Pietrapiana, the Communal Forest of Poggio di Nazza and the private forests that border the villages of Fiumorbu from San Gavino di Fiumorbu to Lugo di Nazza.
Higher up the ZNIEFF is located on the eastern slope of the ridge separating it from the territorial forests of Sant'Antone and Marmano.
The ZNIEFF includes the upper and middle watersheds of the Abatesco and some tributaries of the Fium'Orbu river such as the
Saltaruccio and
Varagno streams.
The area is mainly covered with beech forest (''
