The
Blue Lagoon Nature Reserve is southwest of Bletchley, adjacent to the
railway line. Formerly owned by the London Brick Company, the area has been
landscaped to become an interlocking series of lakes and ponds. The
Blue Lagoon itself used to be a large pit that was used to excavate
clay for brick making. The pit was flooded over 50 years ago when when
the walls collapsed and water from Water Eaton Brook came in. The
shallow ponds are a good place to see dragonflies. Sixteen of the
seventeen species that have been recorded in the Milton Keynes area have been
seen at the lagoon.
You
may also see Grass Snakes at the Nature Reserve. They are good
swimmers and can be seen swimming with their heads above the water. If
disturbed, grass snakes will dive and hide amongst water weeds where
they can remain for up to an hour.
