John Smeaton designed this dam, or weir, on the River Coquet for the Coquet Ironworks in 1777. The dam is located southwest of the historic hamlet of Guyzance, 6.5km from the Northumberland coast.
The dam is founded on solid rock. Its downstream face is a vertical masonry wall, 2.44m high and 2.44m wide. The upstream slope has masonry facing over a rubble core. The structure is arched in plan — making it a horseshoe dam — with the arch pointing upstream. The arch is 49.4m wide and built to a radius of 51.8m.
Coquet Dam survives much as Smeaton left it, despite his comment that, "There is not a more difficult or hazardous piece of work within the compass of civil engineery than the establishment of a high dam upon a rapid river that is liable to great and sudden floods, and such I esteem the river Coquet, and such the dam here proposed".
