Water regulation strategy

‘Slussen and a new water regulation plan for Lake Mälaren’ is part of the rebuilding of the city district Slussen (The Slussen Project) (Ref. 1). In connection with the rebuilding of Slussen, SMHI (Swedish Meteorological and Hydrological Institute) was in 2007 commissioned by Stockholm City to review and propose a new regulatory strategy for the lake Mälaren (Ref. 2). A new regulation prevents floods, reducing the risk of saltwater entering the lake, benefiting the natural environment around Mälaren. Further effects will also benefit the ecosystem of the lake (Ref. 3).
