Blue Lagoon Local Nature Reserve

The Blue Lagoon Local Nature Reserve lies on the site of a former brickworks. Two pits were excavated here. The northern Water Eaton pit was flooded in the 1940's when the Water Eaton Brook broke its banks. Local people subsequently renamed it the Blue Lagoon for its beautiful colour.

This lake, which is around 18 Metres deep, has exceptionally clean water and is rich in fish and other creatures.

The clear water has also proved an attraction to divers and regular dives are organised in the Blue Lagoon by Milton Keynes Sub-Aqua Club

The brickworks were demolished in 1970 and the southern Flettons pit was used for landfill in the early 1980's. This area has now been landscaped into an attractive string of ponds and hills planted with woodland.

The differing histories of the two parts of the site have added to the diversity of habitat which can be seen today.

Around the Blue Lagoon natural colonisation of the spoil heaps has formed grassland and scrub woodland. The grassland is especially rich in plants and animals including some typical of chalk downland but very rare in North Bucks, such as the Common Spotted orchid and the Marble White butterfly.

The re-landscaped Flettons pit with its small ponds has greatly increased the amount of shallow water habitat, home to nationaly rare Great Crested Newts . Between the ponds and plantations areas were left unseeded for wild plants to colonise.
