Santa Espina Reservoir

The Santa Espina Reservoir is a rural site of hydraulic and landscape character located in the surroundings of Urueña, in the region of Montes Torozos, on the valley of the Bajoz river. It is a modest reservoir, built in the fifties to regulate water and support irrigation, although over time it has remained as a space for recreational use, fishing and nature observation. It is about 13 km from the village, in the limestone and gypsum countryside typical of this area of Valladolid. The most interesting part of the visit is its condition as a small inland wetland, with a sheet of water and banks that attract birds, especially as a resting area for migratory birds. In its surroundings there are also elements of riparian vegetation and Mediterranean scrub, and the place lends itself to quiet walks, landscape photography and wildlife observation. The popular name "marsh" itself reflects its local roots and its historical function in the valley. Its current relevance is mainly environmental and recreational: it is part of the natural resources associated with Urueña and is mentioned by tourist and local entities as a point of ornithological interest. There is no specific protection figure for the reservoir in the sources consulted, but there is a clear interest as an enclave of water in a dry territory with a gentle relief, where these points concentrate biodiversity and landscape.
