Main image

Entrepeñas Reservoir is a large man-made reservoir in Castilla-La Mancha, Spain, formed on the Tagus river system and used for water management and recreation.

The reservoir offers extensive open water used for boating, sailing and other water sports, with beaches and marinas developed at key points along the shore. Its surface area and shoreline create a prominent inland water landscape in a predominantly rural part of central Spain.

Created through river regulation and dam construction during the 20th century, the reservoir forms part of regional water infrastructure for irrigation, supply and hydroelectric use. It has since become an established local recreational resource.

The reservoir lies in Castilla-La Mancha, near the provincial boundary areas west of Madrid and close to towns such as Sacedón and areas within Guadalajara province, forming part of the Tagus river basin.

  • Function: Formed by a dam on the Tagus (Tajo) river system, it is used for water storage, hydroelectric generation and recreational boating in summer months.
  • Recreation: The shoreline features marinas, beaches and seasonal tourism facilities concentrated near nearby towns and recreation hubs.
