Morocco is divided in seven major river basins and a number of smaller basins. The seven major basins from North to South are the Loukkos River, the Moulouya River, the Sebou River, the Bou Regreg River, the Oum Er-Rbia River, the Tensift River and the Souss-Massa-Drâa basin. Except for the Loukkos River, all these rivers originate in the Atlas Mountains.There are few inter-basin transfers in Morocco, the most important ones being the Rocade canal from the Oum Er-Rbia basin to the Tensift basin near Marrakesh, a transfer from near the mouth of the Oum er-Rbia to Casablanca and a transfer from the Bouregreg River also to Casablanca. There are tentative plans for a large north-south water transfer project with an average conveyance capacity of around 2.74 million cubic meter/day (0.75 billion m3/year) over 500–600 km from the Sebou River basin to the water-stressed Tensift basin.
