This report was originally compiled in December 2005, but was revised in November 2014 to include additional contextual information, new mapping, and references to the project archives. The site of the present investigation is 40m north of the Dam Banks South Sluice and bridge, west of Moor Road and between Papplewick Lane and Linby Lane. The water system for the Robinson Mills appears to have been constructed between 1778 and 1830, although there may have been a mill (or mills) on this site before that. Evidence of the 1835 map and 1847 estate map, combined with observations onsite, suggest that there may have been several sluices within the Dam Banks section of the Project Area. A two day excavation programme was devised and carried out during July 2005 to investigate the site at Dam Banks in more detail. The investigation revealed new information about the construction and purpose of this sluice structure.
