Summary

Narrow curvilinear earthwork ditches interpreted as the gutters of a 19th century catch meadow irrigation system are visible on aerial photographs taken from 1946 onwards and on visualisations derived from lidar data captured in 2013. The system had likely passed out of use by the late 19th century.

Narrow curvilinear ditches, less than 2m wide, are visible as earthworks on aerial photographs taken from 1946 onwards and on visualisations derived from lidar data captured in 2013. The earthwork channels follow the contours of the south and southwest facing combe slopes and occupy an area of circa 4.22 hectares. They are interpreted as the gutters of a 19th century catch meadow irrigation system which tapped a spring-fed stream 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. No features are depicted in this exact location on the available historic mapping, and any catch meadow here presumably fell out of use by the late-19th century.
