Description

Lake Nordborg is situated in the southern part of Denmark. It was created during the ice age and is a 56 ha lake with a maximum depth of 8.5 m. Until the 12th century it was part of a fiord system. It is surrounded by urban and agricultural areas and is known as a eutrophic lake with generally low secchi depth and consequently very limited macrophyte growth. Macrophytes are dominated by characeans and elodea canadensis.
