History

Since there was the brook where after the construction of embankments and dams in the river Ems in the permanent backwater of his receiving water, were increased siltation of the sole as well as a risk of flooding in the area of the estuary near the underflow result. For this reason, the creek was expanded in some sections between 1987 and 1990. However, a complete expansion could not take place due to lack of land acquisition for essential surfaces so that subsequently considerations for the construction of a detention basin in the east Rietberger were persecuted.

After the city Rietberg won the bid to host the State Garden Show 2008 in April 2006, resulted from this situation the opportunity to include the planned retention and overflow basins in the to be created garden show and thus the objectives of flood protection with a use within the recreation to connect.
