The kind people at Gilkes have sent me some detail behind the Pistyll Hydro I went to see last week o the National Trust property at Pistyll. The Hydro is actually older than I thought. It was delivered in 1903 and to a J.D Goddard. The Goddard of Goddard silver and brass polish. I now remembered that Richard had told me of the connection and that a relation of his who I think was a maid for the family would travel on the Goddard private train to Pwllheli before coming over to their electrically lit Plas Pistyll for holidays. The hydro is a relatively small 8kw and had a 55m drop from the intake at the Church pool down to the turbine building. See below. The Hidden Hydro is revealing itself!
