waterwheels powering three grinding stones, however problems with the water supply in the summer meant that the mill was often not working at full capacity. The mill continued operating until the 1930s after which the buildings quickly fell into disrepair and were demolished in the early 1950s with a small car parking area now occupying the site. The dam wall was damaged in 1967 by dredging work and eventually collapsed in March 2001. The RVCG and Sheffield Council filled in the pond and created a new one nearby with a pond dipping platform. The official opening was on 17 May 2007. Wolf Wheel Was built around 1722 and had one of the largest wheels in the valley with a diameter of . It was owned by the Windle brothers between 1818 and 1852 who used it for grinding knives and razors, after which it was sold to the Water Company. The mill was in regular use until 1918, but a survey in 1934 revealed that the internal machinery had been dismantled. The pond that served the Wolf Wheel is still in fine condition and has received much attention from the RVCG. It is one of four dams that are used by fishermen in the valley and surrounding wildlife includes dragonflies such as the common darter Sympetrum striolatum and the common hawker, Aeshna juncea. Other wildlife includes kingfishers, great diving beetles and amphibians such as the common frog and palmate newt. Hind Wheel Mill This is oldest mill in the valley with a recorded date of 1581 when Thomas Hind, Robert Webster and John Swynden were the owners paying £1 per year rent. It was completely rebuilt around 1820 with production ceasing around 1930. In October 1936 "The Sheffield Daily Independent" reported that the building had completely disappeared. The present day Round Pond which served the mill is one of the most popular in the area being stocked with trout for anglers; the surrounding area has a large variety of wildlife and there is a picnic area. Nether Cut Wheel Situated near the "S" bend on the A6101, the Nether Cut was the last mill to work in the valley; it was still grinding scythes until 1939 and was not demolished until 1956. The mill suffered some unrest and damage during the Sheffield Outrages in 1874 for using non-union labour. Walkley Bank Tilt This began as a mill making cutlery around
