Narrow curvilinear ditches, less than 2m wide, are visible as earthworks on aerial photographs taken in 1946 and on visualisations derived from lidar data captured in 2013. The earthwork channels follow the contours of the northeast and southwest facing combe slopes and occupy an area of circa 5.5 hectares. They are interpreted as the gutters of a 19th century catch meadow irrigation system possibly associated with Ham Farm and which tapped a spring-fed stream that rises circa 600m to the northwest. Catch meadow systems are designed to irrigate pasture by diverting water from a spring or stream. The water is carried along the valley sides via one or more channels or gutters and when irrigation was required the gutters were blocked, causing water to overflow from gutter to gutter, thereby irrigating the slopes. This film of water prevented the ground freezing during the winter and raised the temperature of the grass in the spring, thereby encouraging early growth, particularly important during the hungry gap of March and April. The earthworks only partly correspond with water channels depicted in this location on the late 19th century Ordnance Survey map, suggesting that the system had mostly fallen out of use by this time. Earthwork gutters of other catch meadow systems have been recorded in proximity to the southeast.
