"El río Lucus o Lukus (en griego: , lobo')? tiene una longitud aproximada de 100 km, nace en el Rif (Marruecos) y transcurre por la llanura del Garb y desemboca en océano Atlántico, en Larache. En su desembocadura forma extensos meandros donde se mezclan las aguas dulces y saladas, donde todavía hoy se pescan anguilas y angulas. También se explotan salinas, obteniéndose la sal por evaporación. El río puede provocar grandes inundaciones en época de crecidas. En 1775 aparece en la cartografía de Tomás López y Vargas con la denominación de "Río Lucos""
"The Loukkos River ( ) is a major river in northern Morocco. Although it is relatively short (about 100 km), the river is the third largest in Morocco with an average flow of 50 m³/s. The Loukkos river takes source in the Rif Mountains and flows into the Atlantic Ocean in the city of Larache, the city's port is inside the river. The Loukkos river basin is 3,730 km² and contains one of the most fertile and productive agricultural lands in the country. One of the river's tributaries, Oued Makhazine, bears a great historical importance since it witnessed one of the most decisive battles in the history of Morocco: the Battle of Alcácer Quibir. In the battle on the 4th of August, 1578, the joint army of deposed Moroccan monarch Abu Abdallah Mohammed II Saadi and his ally, king Sebastian of Portugal, was defeated by the army of the new Moroccan sultan from the same Saadi dynasty (who was also Abu Abdallah's uncle)."
