Litani River. The Litani is the longest river flowing entirely within the borders of Lebanon, originating in the fertile Bekaa Valley and emptying into the Mediterranean Sea. Its course and waters have been central to the region's agriculture, history, and geopolitics for millennia. Today, the river is managed by the Litani River Authority and faces significant environmental challenges.

Geography and Course

The river originates from a spring near the ancient city of Baalbek, flowing southward through the agricultural heartland of the Bekaa Valley. It passes by major towns such as Zahle before making a dramatic sharp bend near Marjayoun, where it cuts westward through the Mount Lebanon range. This segment creates the impressive Litani River Gorge before it finally discharges into the Mediterranean Sea just north of the coastal city of Tyre. The river's basin is bordered by the Anti-Lebanon mountains to the east and the Jordan River basin to the south.

Hydrology and Water Management

The river's flow is highly seasonal, fed by winter rains and snowmelt from the Mount Lebanon and Anti-Lebanon mountains. Its waters are extensively regulated, primarily by the Qaraoun Dam, which created Lake Qaraoun, the largest artificial lake in Lebanon. Management falls under the purview of the Litani River Authority, which oversees irrigation projects and hydroelectric power generation. Key infrastructure includes canals like the South Lebanon Canal project, designed to divert water for agriculture in the southern coastal plains.

History and Archaeology

The river valley has been a corridor of human activity since antiquity, with its upper reaches in the Bekaa Valley home to the famed Roman ruins of Baalbek. In the medieval period, the area was contested during the Crusades, with nearby strongholds like the Beaufort Castle playing strategic roles. During the 20th century, the river marked a strategic line in conflicts, notably during the 1948 Arab–Israeli War and later Israeli military operations like the 1978 South Lebanon conflict and the 2006 Lebanon War.

Environmental Issues

The river suffers from severe pollution due to untreated agricultural runoff, industrial waste, and raw sewage from settlements like Zahle and surrounding villages. This has led to eutrophication and toxic algal blooms in Lake Qaraoun, threatening biodiversity. Over-extraction for irrigation and illegal water usage exacerbate water scarcity, while political instability has hampered enforcement by the Litani River Authority and the Ministry of Energy and Water (Lebanon). Regional tensions also influence management, as the river's health is linked to broader regional disputes.

Economic and Agricultural Significance

The river is the most critical water source for irrigation in Lebanon, sustaining vast agricultural lands in the Bekaa Valley and southern coastal plains, producing crops such as wheat, vegetables, and fruits. The Qaraoun Dam provides hydroelectric power, contributing to the national grid managed by Électricité du Liban. Water from the river also supports major industrial activities and is vital for projects like the Litani River Decoration Project aimed at boosting local agriculture. Its management remains a key issue for Lebanese economic policy and development.
