Requejada Reservoir, reservoir in the province of Palencia, Spain

Requejada Reservoir is a gravity dam on the Pisuerga River in the municipality of Cervera de Pisuerga, Palencia. Completed in 1940, its concrete wall is 52.5 metres high and 200 metres long, creating a 65 hm³ reservoir covering 333 hectares. The dam stands at Arbejal and floods the Vañes valley, just downstream from the river's source.

The reservoir was completed in 1940 as part of a broader water management effort to regulate the Pisuerga River and control flooding in the region. For over 80 years, it has supported agriculture and daily life by providing water for irrigation and household use.

The dam stands at Arbejal and floods the Vañes meadow, so the villages of Vañes and Arbejal, in Cervera de Pisuerga, are the reference points for anyone coming to the water. The reservoir lies within the Fuentes Carrionas y Fuente Cobre-Montaña Palentina natural park, and it is not part of the so-called Ruta de los Pantanos, which groups Ruesga, Compuerto and Camporredondo.
