De Klaarkampstermeermolen was originally built in 1862 by the Juckemavaart. It was moved to its current site in 1893 to drain the 210 pondemaat (77 ha; 190 acres) Klaarkampstermeer. The mill was restored in 1975, at which time an electric pump was installed by the mill. The mill was restored in 1991, a cast-iron windshaft replacing one made of wood. A further restoration was undertaken in 2009. The mill is listed as a Rijksmonument, №11695.
De Klaarkampstermeermolen is what the Dutch describe as a Grondzeiler. It is a two-storey smock mill on a single-storey base. There is no stage, the sails reaching almost to ground level. The mill is winded by tailpole and winch. The smock and cap are thatched. The sails are Common sails. They have a span of 16.14 metres (52 ft 11 in). The sails are carried on a cast-iron windshaft, which was cast by Gieterij Hardinxveld of Hardinxveld-Giessendam, South Holland in 1991. It also carries the brake wheel which has 47 cogs. This drives the wallower (24 cogs) at the top of the upright shaft. At the bottom of the upright shaft there are two crown wheels The upper crown wheel, which has 35 cogs drives an Archimedes' screw via a crown wheel. The lower crown wheel, which has 34 cogs is carried on the axle of an Archimedes' screw, which is used to drain the polder. The axle of the screw is 37 centimetres (1 ft 3 in) diameter and 5.15 metres (16 ft 11 in) long. The screw is 1.07 metres (3 ft 6 in) diameter. It is inclined at 25.7°. Each revolution of the screw lifts 293 litres (64 imp gal) of water.
