Thorney Mill on the River Colne

At Domesday, there were three mills in Iver, of which one was probably Thornley. Records from 1842 show that it was occupied by John Owen, and used for paper-making. By 1877 Price and Co. manufactured paper here. Over the years the site was expanded and used for other forms of manufacturing. After the Great War the premises served for a while for paint-making, followed by the manufacture of iron water pipes, but it was derelict by the 1930s although the waterwheel was still in place. The mill has now been converted into residential units. The River Colne is one of the best chalk rivers in Greater London which means it is very clean. It rises in North Mimms Park in Hertfordshire and it flows into the River Thames near Staines. Its basin extends well into the Chiltern Hills thanks to a number of tributaries while to the north its drainage basin is separated from the River Great Ouse which flows into The Wash.
