A stream or leat leaves Agnes Shaft pond (see PRN 42208) & runs south to SX43507327 where it appears to split into two. One branch feeds the upper section of Blanchdown settling ponds (see PRN 42206) at SX43437322 & the other turns to the east to feed the Wheal Thomas/Watson water wheel at SX43627305. The survey in 2002 found the 0.75m wide leat still identifiable in some places. Other details: Sites 314 & 314/1.
