Water and river systems
The Sierra Subbética Natural Park is a veritable reservoir thanks to the abundance of tributaries of the Río Genil to the south, and the Río Guadajoz to the north. The region acts as a connection between these two rivers.
The main tributary of the Río Guadalquivir, the Río Genil, is the source of the largest reservoir in Andalucía: known as Iznájar, it covers parts of the provinces of Cordoba, Malaga and Granada, has a capacity of over 950 million cubic metres, is 32 kilometres long, and has over 100 kilometres of shoreline.
On the surface of the Sierra Subbética, and due to the predominance of limestone rock, smaller rivers and streams are scarcer, and prone to drying up during hot summer periods.
