Type and Period (1)
- None recorded
A post-medieval water meadow of a type known locally as a catchwork or field-gutter system was constructed on a north-west facing slope above the East Lyn River at circa SS 74524802, to the west of the farm at Hallslake, Brendon parish. Catchwork systems are usually found on steep combe sides and are designed to irrigate pasture by diverting water from a spring or stream along the valley sides via a series of channels or gutters. When irrigation was required the gutters were blocked, causing water to overflow, 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. Any excess water then returned to the feeder stream at the valley bottom or was removed by a tail drain. The use of a series of parallel gutters to improve the coverage is a common feature of Exmoor systems. However in this instance the arrangement is slightly unusual. The main water meadow is fed by a channel currently mis-labelled on the Ordnance Survey base map as a drain. This channel is in fact a type of gutter known as a head main which feeds an arrangement of several lateral gutters within a very shallow combe. The source of the water is probably a spring within the farmyard at Hallslake. A second channel or head main, almost flush to the field boundary to the south, is inferred from a visible slick of water the on photographs but was not visible to transcribe from the availabel aerial photographs due to heavy shadow. This system may be an integrated system where the water picks up manure as it passes through the farmstead and subsequently distribute this liquid fertaliser on the slopes. [1-3]
