Monument Number 1465435

Hob Uid: 1465435
Location :
Devon
North Devon
Lynton and Lynmouth
Grid Ref : SS7127046890
Summary : An extensive water meadow of probable 19th Century, of a type known locally as a catchwork or field-gutter system, is visible as a series of ditches or water channels on aerial photographs to the east of Manor farm, East Ilkerton. 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 roughly parallel 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 parallel gutters to improve the coverage, as seen here, is a common feature of Exmoor systems.
More information : A post-medieval water meadow of a type known locally as a catchwork or field-gutter system was constructed on an east facing slope above the West Lyn River at circa SS 71274689, to the east of Manor farm, East Ilkerton, which which it is probably associated.

The use of a series of parallel gutters to improve the coverage, as seen here, is a common feature of Exmoor systems.
This system may be an example of an ¿Integrated¿ system, where the water passes through, or is otherwise connected to the farmstead, where it picks up manure and subsequently distribute this liquid fertaliser on the slopes.
A more modest system can be seen across the river on the west facing combe slopes of the West Lyn River.
