Reservoir marked on the 1889 OS above Cae'r gors farm. An earthen bank 19m long E-W and 1m high was built to dam a natural stream and create a reservoir approximately 19m by 12m. The outflow was probably in the centre of the dam, where a C20 pipe still exists, but the dam has been breached here.
Recorded as part an Uplands Initiative field survey.
