Summary
Leat in three sections. This leat now dry and silted was apparently constructed to convey water for about two miles from the head of one stream to the head of Lanson Brook. It may have augmented the supply for streamworking the Lanson Brook valley, or enhanced that of the Sherberton potwater leat.

(25/04/1989) Leat in three sections. This leat now dry and silted was apparently constructed to convey water for about two miles from the head of one stream to the head of Lanson Brook. It may have augmented the supply for streamworking the Lanson Brook valley, or enhanced that of the Sherberton potwater leat.
It can be first traced adjacent to Bull Park (SX 60237330) at 376m OD and is well defined in the inbye (SX 60227358). It follows the 374m contour around the W, N & E flanks of Royal Hill, occasionally through patches of large earthfast boulders. It terminates at
SX 62037213 at approximately 372m OD in the upper reaches of Lanson Brook. It is on average 1.7m wide and 0.3m deep with an earthen upcast bank on the downhill side and is, at maximum, 2.3m wide and 0.8m deep with a substantial bank on the lower side.
