The dam wall on the east side of the reservoir is 152m long and 10m wide, comprising a wide stone bank capped with turf. Details of the associated water courses and storage system are held within the Plas Tan y Bwlch Industrial Archaeology Archive for Rhos Slate Quarry. The reservoir is depicted on the 1st edition 6" Ordnanace Survey map of 1891.M.Railton, NPA, 9th December 2010.
