Book excerpt: This case study is about a Dutch shallow freshwater lake; the Veluwerandmeren. There are two Dutch Iakes in the HMW case study project; the Veluwerandmeren and Lake Loosdrecht. The lakes have been influenced drastically by hydromorphological changes. Both lakes have different water authorities: The Veluwerandmeren are managed by Rijkswaterstaat, acting on a national scale. Lake Loosdrecht is managed by the Water boards, acting on a regional scale. The Veluwerandmeren have been selected as a case, because it is the product of the building of dikes and the reclamation of a polder. Therefore, the Veluwerandmeren are to a certain extent comparable to a number of relatively large Dutch shallow Iakes (e.g. Lake IJssel, Markermeer). The lake is relatively young (1955) and has a unnatural morphology as a result of the reclamation of the polder. The present lake has numerous human uses, and a history of large hydromorphological impacts. Due to these impacts it has no stable period of relatively undisturbed ecological functioning. This makes the Veluwerandmeren an interesting case. Moreover, the Veluwerandmeren have been selected, because its functioning has been studied extensively. There are many data and studies available for this case study.
