Omschrijving en wateranalyse Haarlemmermeersebosplas
De Haarlemmermeerse bosplas
De grote waterplas in het Haarlemmermeerse Bos is in de
jaren 1973 – 1977 ontstaan door winning van circa 3 miljoen
m3 zand tot een diepte van circa 25 meter.
Het oppervlak van de waterplas is circa 25 hectare.
Na beëindiging van de zandwinning in 1977 is het terrein rond
deze waterplas ingericht als recreatiegebied annex stadspark
van circa 115 hectare groot.
In 1979 is het opengesteld voor het publiek en sindsdien heeft
het zich ontwikkeld tot een regionaal recreatiegebied dat meer
dan 400.000 bezoekers per jaar trekt.
