Major Bodies of Water in Morocco: Atlantic, Mediterranean, and Inland Waters

Morocco's water geography defines its climate, economy, and history. With coastlines on two major marine bodies and a network of rivers, lagoons, and reservoirs, water shapes the kingdom from the Rif to the Sahara.

Marine Bodies

• Atlantic Ocean: 1,835 km coastline (west); cold Canary Current; rich fisheries (sardines, octopus); major ports: Casablanca, Mohammedia, Safi, Agadir, Dakhla
• Mediterranean Sea: 468 km coastline (north); warmer, saltier; ports: Tangier Med (Africa's largest), Nador, Al Hoceima
• Strait of Gibraltar: 14.3 km narrowest point; connects Atlantic-Med; strategic chokepoint; Tangier (Morocco) ↔ Gibraltar (UK) / Ceuta (Spain)

Coastal Lagoons & Estuaries

• Nador Lagoon (Mar Chica): 115 km²; separated from Med by sandbar; Ramsar site; aquaculture, birdlife
• Gulf of Al Hoceima: Small Mediterranean embayment; fishing, tourism
• Oualidia Lagoon: 15 km²; oyster farming, salt pans, birdwatching
• Khenifiss Lagoon: Sahara coast; Ramsar; flamingos, migratory birds

Major Rivers (West-Flowing to Atlantic)

Major Dams / Reservoirs

• Al Wahda (Oum Er-Rbia) — 2nd largest in Africa (3.8 km³)
• Bin el Ouidane (Oum Er-Rbia)
• Hassan II (Moulouya)
• Mohammed V (Moulouya)
• Idriss I (Inaouen/Sebou)

Water Challenges

• Scarcity: <500 m³/capita/year (water stress threshold)
• Overexploitation: Groundwater mining (Souss-Massa, Saïss)
• Climate change: -10–20% rainfall by 2050; +2–3°C
• Policy: National Water Plan 2020–2050: desalination (Casablanca, Agadir, Dakhla), wastewater reuse, demand management

Morocco's water wealth is real but uneven—Atlantic abundance, Mediterranean access, Atlas snowpack—yet every drop is accounted for in a nation where water is development.
