MMO3008 - Post-medieval water meadow south of Lanacre (Monument)

A water meadow of probable post-medieval date can be seen on aerial photographs of the 1940s, as earthworks on the south facing valley slopes overlooking the River Barle to the south of Lanacre, centred on circa SS 8221 3623. It is probably of a type known as a catchwork, ditch gutter or field gutter system. Catchworks were designed to irrigate pasture by diverting water from a spring or stream along the slope via a series of roughly parallel channels or gutters, although simple examples consisting of only a single gutter are common. 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 the March and April. The water-meadow can be seen in use on aerial photographs of 1947, and the gutters remain visible on aerial photographs of 1962. The gutters are not visible on later aerial photographs and may have been levelled by post war improvements.
