Hollands Diep. 29/08/00; Zuid-Holland; 4,139 ha; 051°42’N 004°30’E; Natura 2000 (SAC, SPA). The Ramsar Site boundary has been aligned to the Natura 2000 site, resulting in an increase of 247 ha. The Site, a former estuary in the Meuse-Rhine delta, is now a freshwater lake after its separation from the North Sea in 1970 by the Haringvliet dam. Hollands Diep is an especially important area for breeding waterbirds such as the Eurasian spoonbill and barnacle goose, and a valuable spawning, nursery and feeding ground for threatened fish species such as barbel and other migratory fish including sea lamprey and salmon. The Site plays an important role in flood regulation and sediment trapping. The lake and the adjacent land are used for forestry, farming, commercial fishing, shipping, water management, conservation and research. Factors adversely affecting the Site’s ecological character include industrialization (in particular the construction of wind turbines), urbanization, eutrophication and water pollution. A management plan for the Site is currently being prepared. Ramsar Site no. 1273. Most recent RIS information: 2013.
