The Board House is a building used for meetings by United Utilities and is located on the western shores of the reservoir, near the Hodder Water Treatment Works.

It was created in 1932 by the Fylde Water Board by flooding the Dalehead valley and the surrounding farmland, including the hamlet of Stocks-in-Bowland from which the reservoir derives its name.

At the peak of the construction project, over 500 men worked there and most of them lived in a temporary village called Hollins.

[1] Prince George officially opened the reservoir by unveiling a commemorative bronze plaque.

Steam traction engines hauled building material between the Tosside railhead and the water board depôt adjacent to Long Preston railway station.
