Full Description

A contour-following leat noted by McDonnell [1] on air photos [2] on the W side of Cheriton Ridge. [1,2] SS 7417 4500 to SS 7376 4634. A catchwater leat used to irrigate spring grass on a west facing slope. It is some 3.5 km long, probably for early watering of fields and use at Cheriton Farm. The leat is shown on the OS maps dated 1888 [3] and 1904 [4]. No survey action was carried out. [6] The does not appear to continue as far north as Cheriton and therefore may not have been associated with watering here. Its precise function remains uncertain. [7] The leat runs from just north of the Forest boundary, where the remains of a collapsed stone bridge or sluice at the take off point can be seen at SS 74830. The northern end of the leat, where it leaves the common, has not been established, but the channel is substantial and takes water from several streams which flow into Hoaroak Water, suggesting it may have been built in the late 19th Century to power farm machinery at farms in Cheriton.
