Lake As Pontes: The Artificial Lake of Spain

Nestled in the lush, green landscapes of northwestern Spain, Lake As Pontes (Lago de As Pontes in Spanish, Lago das Pontes in Galician) is one of Europe’s most notable examples of ecological restoration. Once a large open-pit lignite coal mine located in the municipality of As Pontes de García Rodríguez, Galicia, it has been transformed into Spain’s largest artificial lake—a magnificent 865-hectare body of freshwater that represents a transition from industrial activity to environmental renewal.

From Industrial Powerhouse to Ecological Sanctuary 

For more than three decades, from 1976 to 2007, the site was operated by energy company Endesa, extracting over 260 million tonnes of lignite to power the local thermal power plant. The mining operation created a massive crater approximately 5 kilometres long, reaching depths of up to 300 metres.

Once mining activities stopped in 2007, local authorities and environmental engineers launched a major effort to flood the site. Over four years, from 2008 to 2012, rainfall, water diverted from the nearby Eume River, and local runoff slowly filled the huge void, forming a reservoir capable of holding more than 540 million cubic metres of water.

A Hub for Nature and Recreation
  
Today, Lake As Pontes is much more than an engineering achievement; it is a flourishing area for biodiversity and outdoor activities. The surrounding hills, now heavily reforested with native plants, attract a wide range of bird species, making the area a popular spot for birdwatching. The lake includes a 400-meter-long artificial sandy beach that attracts both residents and visitors during the summer months.

Its steady and calm wind conditions make it perfect for:
- Sailing and Windsurfing: Frequently hosted by local sports clubs.
- Kayaking and Stand-Up Paddleboarding (SUP): Ideal for enjoying the smooth and wide waters.
- Hiking and Cycling: A network of trails runs along parts of the lake’s edge, offering clear views of the bright blue water.
Lake As Pontes serves as a powerful example of how damaged industrial landscapes can be redeveloped into sustainable, vibrant aquatic ecosystems, benefiting future generations.
