A system of at least seven post medieval drainage ditches is visible on aerial photographs at Sparcombe Water Head. The ditches were possibly cut as part of the Knight family's attempt at agricultural improvement associated with the construction of Tom's Hill Farm around 1850. Centred on approximately SS 81934149, this drainage system covers an area of roughly 0.7 hectares. Similar, but much more extensive drainage systems are visible to the north and west towards Warren Farm, some draining into natural streams and water courses, others appearing to drain into the various contour leats.
