Awali River

The Awali River (Arabic: / ALA-LC: Nahr al-Awal, ancient Bostrenus / Bostrenos) is a perennial river in Southern Lebanon. It was known as the River Asclepius in ancient times. It runs over 48 kilometers (30 miles), beginning at 1,492 meters (4,895 feet) on the Barouk peak and ending at the Niha mountain.

Two tributaries, the Barouk and Aaray rivers, feed into the Awali. In its higher reaches, the Awali is also known as the Bisri river, flowing down the western face of Mount Lebanon and into the Mediterranean. The Awali river has a discharge of 10.1625 m3/s (358.89 cu ft/s) and flows across a 294 km2 watershed (114 sq mi).

The Awali River empties into Joun Lake, which is part of the Bisri Dam project, which aims to increase the region's fresh water supply. In September 2020, the World Bank decided to cancel a substantial amount of the Bisri Dam project's funding.
