Litani River Dam

Qaraoun, an artificial lake of 11 square km, was created by the Litani River Dam, 60 meters high and 1,350 meters in length, which was completed in 1959. A spillway of 6503 meters carries the water to the underground station where generators produce a maximum of 185 megawatts of electricity, the largest hydroelectric project in Lebanon. The dam was intended eventually to provide irrigation for 310 km² of farmland in South Lebanon and 80 km² in the Beqaa Valley. The office is at the southern (dam) end of the lake on the left side. The lakeside has a hotel and a number of restaurants specializing in fresh trout.

The Litani River Authority

The Litani River Authority (LRA) was formed in 1954 to facilitate the integrated development of the Litani River Basin. Shortly after its formation, the LRA engaged in a massive hydroelectric development project that tapped the 850 meter head potential between Lake Qaraoun and the Mediterranean. This development has brought about major hydrological changes to the Litani River Basin, where the flows from its upper reaches above Lake Qaraoun, referred to as the Upper Litani Basin (ULB), are diverted through a system of tunnels, ponds and plants, to meet the Mediterranean several kilometers north of its original natural tailwater. These changes have resulted in the effective hydrological separation between the ULB and the Litani lower reaches.The advent of a protracted civil strife in the 1970s followed by a prolonged occupation in the 1980s that lasted into the 1990s, have plunged the country into disarray, freezing development and investment in infrastructure. The subsequent return to normal conditions has encouraged the LRA to initiate several major water diversion projects from the ULB worth hundreds of millions of US dollars.
