This long river rises in the
Sierra de Gúdar, near
Villarroya de los Pinares and
Miravete de la Sierra in the
Maestrazgo, Aragon. It receives water from rivulets originating in the
Sierra de la Cañada and
Sierra Carrascosa. Flowing northeastwards its waters fill the
Santolea reservoir, then the dam of
Calanda, before it enters the
Ebro at
Caspe. In addition to the towns mentioned, it also flows through
Alcañiz and
Civan. Tributaries of the Guadalope include the
Bergantes,
Fortanete,
Bordón and
Mezquín on the right side, and the
Aliaga River and the
Guadalopillo on the left. == See also ==
