About
Østensjøvannet () is a lake located in the Østensjø borough in Oslo, Norway. It is well known for the wide variety of birds and other wildlife that can be found there. It is currently a wildlife preserve, though urban development posed a serious threat to the lake and its environs during the 1980s and early 1990s.
