Every field in the record above is taken from the references below. A field that none of them confirms prints as a dash.

  1. BAUER Spezialtiefbau, Dam work for Jannah Dam in Lebanon. geotechnical-solutions.bauer.de.
  2. The structure is an arch-gravity dam holding 38 million m3 to supply Byblos, Beirut and the surrounding area.
  3. BAUER Lebanon Foundation Specialist built 9,500 m2 of clay-concrete cut-off walls to a depth of 50 m, parallel diaphragm walls joined by an arch-shaped bulkhead giving stability to 36 m, and grout curtains along the dam foundation and in the abutments.
  4. The scope was diaphragm walls on the upstream and downstream cofferdams plus drilling and injection, in the period August 2017 to January 2020. Lebanese Ministry of Energy and Water, Jannah Dam. energyandwater.gov.lb.
  5. The dam sits on the Nahr Ibrahim at Jannah in Jbeil, is expected to hold 38 million cubic metres, and is to feed Kesrouan, Jbeil, Beirut and wide areas alongside Chabrouh Dam.
  6. The study of the scheme was drawn up in 1954 and the ministry let it to engineering offices with Lebanese and foreign experience.
  7. Beirut and Mount Lebanon Water Establishment, 2026 Vision. ebml.gov.lb.
  8. Under development of water resources the establishment lists completion of the Jannah Dam and the drawing of its water to Beirut and its suburbs as an objective, so the dam is neither finished nor delivering water.
  9. MTV Lebanon, Qartaba court requests suspension of Jannah dam works, 19 September 2014. mtv.com.lb.
  10. The court asked for works to stop pending an expert geologist's report on environmental and public safety claims.
  11. Stage is recorded as Stalled because the last documented works ended in January 2020 and the intended operator still carried completion as an objective in 2026. No source opened states that the reservoir has been impounded, that the dam has been commissioned, or that the project has been formally abandoned, and no cost figure rests on a page that could be opened.
  12. Coordinates added on 20 September 2026, approximate.

gives 34.0801 35.8336 and marks the point approximate. OpenStreetMap maps no dam on this reach of the Nahr Ibrahim, and the only water body near the site is a 0.6 ha pond, so the pin is given to two decimals and stands for the Janneh locality, which Nominatim places in the Byblos district of Keserwan-Jbeil.
