The Oploo Water Mill is an un-named mill located on Watermolenstraat in the town of Oploo. The mill was built in 1725, and over the years has been used as an oil, grain, and barley mill. The stream that the mill stands on is quite a small one, and because of this the mill could only run well during the winter. The Oploo Water Mill was restored in 1969, and is still in use today. The mill is open to the public on the first Saturday of each month.
