Hydrography

river

The hydrographic network of the region is made up of the Segura river and its affluents:

* Mundo river (which is born in Albacete), it is the one that contributes to the Segura with the greatest volume.
* Alhárabe river and its affluent, the Benamor.
* Mula river.
* Guadalentín, Sangonera or Reguerón river (which is born upper before Lorca).

Due to the water supplying incapacity of the Segura river basin, contributions to this river basin are made, originated from the basin of the Tajo river, by means of the Tajo-Segura trasvasement.

Seas

The greatest natural lake of Spain can be found in the region: the Mar Menor (Small Sea) lagoon. It is a salt water lagoon, adjacent to the Mediterranean Sea. Its special ecological and natural characteristics make the Mar Menor a unique natural place and the largest saltwater lake in Europe. With a semicircular shape, it is separated from the Mediterranean Sea by a sand strip 22 km in length and between 100 and 1200 m wide, known as La Manga del Mar Menor (the Sleeve of the Small Sea). The lagoon has been designated by the United Nations as a Specially Protected Zone of Importance for the Mediterranean. Its coastal perimeter accounts for 73 km of coast in which beaches follow one another with crystal clear shallow water (the maximum depth does not exceed 7m). The lake has an area of 170 square kilometers.
