HLF Restoration Project
The Friends of the Porter Valley were instrumental in organising the 2010-12 conservation project, which involved the dredging and repair of the dam (including installing a liner), repair works to the buildings, and the restoration of the pentrough, water wheel and all internal machinery.
It also comprised the creation of improved visitor facilities, including an extended courtyard area with a timber shelter and a range of interpretation and education material.
As part of the project the buildings were surveyed and photographed to provide a complete archaeological record before restoration. While the dam was dredged the opportunity was taken to photograph the inside of the retaining wall prior to the new earth retaining bund being constructed.
