(16/09/1994) A probable leat runs for some 350m from NGR SX 5799076046 to SX 5827076252. The shallow silted channel is 1.2m wide and 0.3m deep. It is disturbed by vehicle tracks at its northern end. The continuation of its course has been plotted from air photographs (Authority 1); it may have brought water from Blackbrook River to the nearby openwork (SX 57 NE 101). Four small tin pits are located to the north and south of this leat at NGR SX 58157619 and SX 58077605.
