Blue Lagoon Local Nature Reserve

Local nature reserve in Buckinghamshire, England

The Blue Lagoon Local Nature Reserve is a Local Nature Reserve in Bletchley, Milton Keynes in Buckinghamshire, United Kingdom. The Blue Lagoon is the only Local Nature Reserve in the City of Milton Keynes. The diverse habitat, including shallow and deep water, grassland, scrubland and woodland, hosts an abundance of fauna and flora. The Blue Lagoon is also extensively used as a recreational facility.

The Blue Lagoon lies on part of the site of former brickworks (the neighbouring site to the west is now a landfill site). Bletchley lies on the Oxford Clay Belt and the manufacture of bricks was a major industry in Bletchley between when the brickworks were first opened in the 1890s until the development of Milton Keynes in the 1970s. The works on the Blue Lagoon site were closed in 1970 The pure blue colour of the pit gave the lake its colloquial and now official name. They have planted a bus, two cars and a light aircraft to explore. There are also a further six sunken boats and concrete pipes on the lake bed. The lake supports a diverse ecosystem: pike, perch, roach, crayfish are often reported and tench and carp are occasionally seen. As such, the lake is used as an angling site. The area around the lake is predominantly wooded. The southern section of the reserve, around what remains of the Flettons pit, is landscaped around former spoil heaps. The area contains scrub and grasslands and is rich in plants and animals, including some abundant in chalk downland areas but rare in Milton Keynes.
