Location

The Lac de Tolla is formed by a dam (Barrage de Tolla) on the Prunelli river. The Ruisseau d'Agnone and the Ese River also empty into the lake. It is in the commune of Tolla just south of the village of Tolla. The D3 road runs along its north shore.[1] Lake Tolla is at an altitude of 550 metres (1,800 ft). There is a belvedere on the heights above the lake from which the dam can be seen.[2] It is less than an hour's drive away from Ajaccio.[3]

Dam

The Barrage de Tolla was built between 1958 and 1960, and was commissioned in 1965.[3] It is owned and operated by Électricité de France (EDF). It is a gravity dam 87 metres (285 ft) high and 120 metres (390 ft) long with a crest elevation of 563 metres (1,847 ft). It impounds 34,740,000 cubic metres (1.227×10⁹ cu ft) of water.[4]

Between 3 November and 20 December 90,000,000 cubic metres (3.2×10⁹ cu ft) of water entered the reservoir, three times its capacity. Typically the reservoir would receive five times its capacity of water each year. On 20 December 2019 the Fabien storm caused the dam to overflow, but the structure was not damaged. When producing the maximum amount of electricity the dam releases 11 cubic metres (390 cu ft) of water per second. At the time of the flood the inflow was 20 cubic metres (710 cu ft) per second.[5]

Swimming, kayaking, paddling, etc. are allowed, but motorized boats are not allowed. Anglers may fish for pike, pike perch, perch, carp, roach and catfish.[3]
