A derelict structure at the north west corner of the lake was investigated. The steps down towards the silted up lake suggested it was a slipway or a boathouse. Further investigations make this seem less likely. The structure has a flagstone floor and is bricked in at the lake end. Inside it was rendered. All of this suggests a different use – perhaps a plunge pool for a bracing dip by the lake, or a holding tank for fish.

Possible boathouse structure before excavation.	The same structure, excavated by volunteers from RWE npower.	Volunteers from RWE npower continue the excavation.
Detailed drawings are done. The ‘boathouse’ now looks more like a plunge pool.
