The Dutch Nationaal Archief - one of the hosts of the GLAM-WIKI 2015 conference - has started uploading a series of public domain images from the archives of the Dutch Rijkswaterstaat to Wikimedia Commons. According to its mission statement, Rijkswaterstaat is "the national agency that provides dry feet, clean and sufficient water and a quick and safe flow of traffic" The images mainly depict (sometimes historical) waterways, locks and bridges in the Netherlands.
