Mill dam, mill race, weir and sluice gates for the former Rishworth Mill

The mill dam, mill race, weir, and sluice gates for the former Rishworth Mill are constructed from stone-lined channels, iron, and wooden and stone sluice gates. The feed for the mill dam comes from Booth Dean Clough, which flows northward through the area of Rishworth Mill towards Ripponden. There is a weir on the stream, from which a leat diverges to the east, featuring a sluice mechanism with iron uprights and stone plates; only part of the winding mechanism remains. The leat travels through a narrow stone-lined channel to the southeastern end of the mill dam.

The dam itself is elongated and oval, aligned from southeast to northwest, with a stone-lined outlet at the northern end and the remnants of a wooden gate nearby. The outlet race flows north in a stone-lined channel, leading to a sluice gate that retains a wooden and iron winding mechanism, complete with a ratchet and wheel. An overflow channel branches off the race halfway along its west side, joining Booth Dean Clough at a lower level. Beyond the top sluice, the race runs underground beneath Rishworth Mill Lane, heading towards the remaining mill buildings to the north.
