The Duke of Edinburgh (third from left) observes border dyke irrigation at the Winchmore Research Station Irrigation Scheme. In a border dyke irrigation system, when water is diverted from the main water races into smaller ones, a temporary dam must be created at the outlet to each border, so the water spills through onto pasture.
