Rivelin Valley Conservation Group
Located about 100 m upstream of the mill dam, the weir of uncut stones is in fairly good condition, providing a sparkling cascade of water when the river is high. The weir deflects water through a small inlet and into a long, wide head goit.
The wide overflow (now also forming an attractive waterfall) is situated at the west (head) end of the mill dam; grooves for washboards (used to raise the water level) can be seen in the stonework on either side. The overflow level was adjusted by the RVCG to allow more water to fill the dam (a delicate operation that took some time to get right because if it is raised too much the dam leaks). Part of the west end of the wheel building and part of a substantial wall that formed support for the pentrough can still be seen. The supporting wall of the Frank Wheel mill dam is unusual in that in parts it lacks the usual protection of an earth embankment.
The tail goit is culverted beneath the track to the east, and runs directly into the head goit of the Wolf Wheel mill dam (next downstream).
A stone monument at the bottom of the bank by the path commemorates the first ten years of the RVCG.
