The High Mill and the Low Mill
These drainage mills are at the eastern end of the area, behind the high boezem of the Overwaard. They both lift water between 1.2 metres and 1.4 metres higher.

The High Mill was built in 1740. It is octagonal, has a thatched roof and rests on a brick foundation. Its sweep covers 28 metres and its lifting mechanism is an Archimedean screw measuring 1.8 metres in diameter. The Archimedean screw replaced the waterwheel in 1962. The mill was built for the purpose of draining Nieuw-Lekkerland's upper polder.

The Low Mill was built in 1761. Like the High Mill, this mill is octagonal, has a thatched roof and rests on a brick foundation, but its sweep is slightly shorter, namely 27.5 metres. It has a waterwheel made of iron measuring 5.3 metres in diameter for lifting water. This mill was built to drain the lower part of the Nieuw-Lekkerland polder.
