Parc de l'Agulla, reservoir in Catalonia, Spain

Parc de l'Agulla is an artificial lake and park north of Manresa, beside the Santpedor road. Its dam was begun in 1966 and the lake, lined with concrete slabs, entered service in 1974. It stores about 200,000 cubic metres over 64,000 square metres, with a maximum depth of 4 metres. The park, opened in 1977 and remodelled in 1986, has 622 trees of twenty species, play areas and swings, and monuments to the Sèquia and to the dog, the faithful friend, with verses by Amado Nervo.

The lake was constructed between 1966 and 1974 as a modern water storage facility to supply Manresa from the medieval Sèquia irrigation channel extending 26 kilometers across the region. This project continued a thousand-year tradition of water management that had shaped agriculture and water supply in the area.

The name comes from the water distributor of the Sèquia: at this spot the channel once split into two canals, and "agulla" was formerly the word for a canal or irrigation ditch. The park was inaugurated in 1977 during the Festes de la Llum, the city's festival of light, and was remodelled in 1986. It holds monuments to the Sèquia and to the dog, the faithful friend, with verses by the Mexican poet Amado Nervo, and a broken column dedicated to Josep Maria Vives i Llambí.

The park lies beside the Santpedor road, north of Manresa city centre, where the Sèquia channel empties into the lake. It has wide play areas and swings for children of different ages, plus walking paths and picnic spots around the water. The lake is linked directly to the city's water treatment plant, so swimming is not part of the visit.

The lake's carp act as living water-quality monitors: if the Sèquia water were contaminated, they would die quickly and warn of the danger. The park also holds monuments to the Sèquia and to the dog, the faithful friend, with verses by the Mexican poet Amado Nervo, plus a broken column dedicated to Josep Maria Vives i Llambí.
