But after it had been overgrown in more than 100 years they choose in 2004 to recreate the lake which was a part of the project Tinnerbäcken which was one of Linköping municipality's LIP projects (local investment programme for ecologically sustainable development) which was implemented in 2002-2004. Today they have recreate lakes and wetlands for the benefit of animals and plants .

At the beginning of summer, in May and June are the nesting for the lake’s all species.

In the fall in October and November, swans come back and they stay as long as the Lake is not completely iced.

When there is bad weather, comes the country's three species of swallows and in the evening comes the bats that want to eat newly hatched insects.
