Weir and Associated Water Management System

MATERIALS: Stone, ashlared and rubble.

PLAN: The pond is situated along the western edge of a small, steep-sided valley. It is divided into two unequal parts with the main pond roughly rectangular in shape whilst the smaller pond at its northern end is apsidal-shaped. The water is controlled over the change in ground level between the two ponds and the stream by three weirs and a sluice outfall.

EXTERIOR: The stone wall of the dam extends along the northern edge of the larger pond. From the centre of the dam a stone-paved spillway extends northwards from under the triple-arched, picturesque bridge which is constructed of ashlared stone. At the eastern end of the dam are masonry linings to a spillway controlling the overflow channel. At the western side is a semi-circular sluice outfall built of rubble stone which has a lintel carved with the date 1779. At the north-west tip of the smaller, apsidal-shaped pond, is another weir with masonry walls which controls the outflow.
